Canon TS6020 Printer, 271 Cartridges

Posted in printers, Uncategorized with tags , on August 14, 2017 by marksun

In March 2017 I bought a Canon TS6020 printer (Amazon $100) which came with a full set of ink cartridges.  At the same time I bought $100 worth of replacement cartridges since two kinds of inventory are required;  black 270 and  cyan, yellow, magenta and black 271 cartridges.

The first ink cartridge to go was the big black 270 ink cartridges ~ May/June.
August 2017, I’ve replaced two cartridges, cyan last week, Magenta today, and tomorrow or soon, Yellow.

To restock:  Canon CLI-271 Value Ink Pack  ~~ $52 Amazon – with four CLI-271 (yellow, cyan, magenta, black), obviously to back up the ink inventory.  At $13 per cart, this is no bargain but one can do worse.

So guesstimate the cost :  If we’ve spent about $100 in ink and printed 1.5 reams of paper (750 sheets) , the cost is about $.13 per sheet just for ink and $.014 for paper or about $.15 per sheet or $72 per ream.

I suppose we need to add the depreciation of the printer over an expected life of 7 years, and add the cost of obsolete cartridge inventory at end of life.  <SIGH>

 

 

Robocopy

Posted in windows with tags on August 6, 2017 by marksun

August 2017-
While I use it, Robocopy can produce unexepected behavior, and worse, not backup files. I’ll accept the fault as my own for not completely reading or understanding everything available on robocopy. As I discover problems, I’ll try to update here.  I’d be pretty happy with tar or cpio, but it is what it is.

This is pretty good:
https://community.spiceworks.com/topic/358653-robocopy-incremental-copy-mir-or-xo-what-s-your-choice

robocopy %home%\Pictures %mybk%\Pictures  /XO /FFT
This command does not backup new files and directories on my %home% directory!  I fully expected it to copy new files and folders but IT DOES NOT.  No idea why.

To make it copy all files I added /MIR and got rid of /XO
robocopy %home%\Pictures %mybk%\Pictures /MIR  /FFT

/XO  I had this there to prevent robocopy from copying files that already exist but this may in fact prevent it from copying files that DONT exist on the destination!  removing it.

/FFT is absolutely necessary to make timestamp comparisons work between Windows7 and the LINUX OS on the backup drive – a WD MyBook.  The backup will fail silently without /FFT.

/MIR is supposed to mirror the file dirs of source and destination.  if a file is deleted on the source, it should delete on the destination!

Below are current (aug2017) settings   – in this case for a single \Pictures  directory

set home=”C:\users\xxxxxxx”
set mybk=”Y:\xxxxxxxprofile”

echo Picture Backup Start
pause
robocopy %home%\Pictures %mybk%\Pictures /MIR /FFT

Oceanic Cable Internet Outage 28may17

Posted in Computers, Networks with tags , , on May 29, 2017 by marksun

Oceanic Cable lost internet service, among other things on Sunday night … came up at 0900 Monday, down at 0930, back up finally 1120.   It could well have been a problem caused as a side effect of work on restoring  local TV feeds, apparently still down 24 hours later, but no idea really what the issue was.

Notes on this event.  I guess the main think is that when the internet comes back, all devices start working by themselves.  User need not do anything but wait, so no action at all is required.

Indications on my SURFboard SB6144 DOCSIS 3.0 cable modem were only two blue LEDS lit.  Normally we get two solid blues ( receive and send) and a flashing blue ( router connection)

Failure mode:

  • Blue receive data,
  • Blue Gig E mode light ( indicator that the router is connected).

 

 

 

Samsung Galaxy S8 – Samsung UN40MU6300 TV – Samsung Connect Issues- Fixed?

Posted in cellphone, TV with tags , , on May 21, 2017 by marksun

If all is well with your S8 to Samsung TV I’d like to know what you’re doing right!  I just bought a new Samsung UN40MU6300FXZA TV to replace a Sony Bravia.  On standup, this TV found my S8 immediately and brought up the “planetaiea” wireless network quickly – seamingly seamless.   Feature-wise and useability, it’s a step up from the old Sony.  The Samsung interface is, ok.

Soon after standup, I find  Samsung Connect, which allows the phone to connect to my TV has some problems, and the closely related Smartview does not work at all.  Initially I was able to watch TV on my phone, nice, bit short range, but it worked. That stopped working the next day and so far it’s still down.

So … issues

The Android Playstore Smartview app does not connect to the TV … it does find “planetaiea tv” but just spins and eventually crashes.  Smartview is a black box to me.  The term is used to refer to the screen mirroring feature, and that seems to be independent of the Playstore Smartview app.  Seems to be a mess – some features work, some don’t. Sign of a marketing term for a collection of unrelated or poorly integrated functions … don’t know.

Samsung Connect app on my S8 phone however does work.  There’s a lot there, five major functions.   Three out of five functions (60%) work. as indicated by the green function list below, but “view tv on phone” has stopped working.

  1. Remote:
  2. Browse Content
  3. Mirror Screen (Smart View)
  4. View TV on phone
  5. Play TV sound on phone – suffers from short range and intermittent signal

Remote works but cannot turn the TV on.  I believe it’s because the TV requires an IR blaster to initially turn on.  After that, a wifi based comm allows the phones remote to work.

View TV on phoneworked on day one, but now no longer connects. Browse Content does not work.  Both apps use Smartview.  Browse content shows two instances of my tv “planetaiea TV”.   Smartview may be a problem.  Uninstall/reinstall. 5/21/17. 1054. No difference. spins on “Connecting to planetaiea TV”.
Google Smartview results are sparse – but there are  rumors of Playstore complaints, and some rumor or of Samsung making changes.  Samsung says nothing helpful, only restates their marketing vision and offers no technical support or any evidence of application updates.   

So far my experience of the phone / tv package is mainly positive – it breaks into new ground with three out of five, but the 40% feature failure is telling.   Amazingly, it’s not a deal breaker because the feature failure are bleeding edge bells and whistles – not the main reasons I have a TV and a cell phone.  I’m mainly happy with both phone and TV.

Restarted the TV setup …  5/21/17
No functional change.  When I try View TV on Phone, black screen for a few seconds, then disconnect.  I see places where there are two S8 phones registered on the TV … could there be duplicate record that is messing up the authentication?  Anyway, it’s for sure a bug and could be a bear as well.

Uninstalled SmartView 5/21/17  — no impact

View TV on Phone – working 
5/28/17 With the TV off,  for no reason, tried View TV on phone … now it works! In addition, the TV itself was off and remains off.  I can turn on the TV with the phone.  I changed nothing … what happened?

Browse Content – requires SmartView –  loaded – does not work – uninstall-  5/28/17

Canon MP640R Printer B200 Error

Posted in Computers with tags on March 22, 2017 by marksun

Looks like the end of the line for the Canon MP640R printer.  Out of the blue, we get this B200 error  with the onscreen message to “remove the power connector and call the service center.”

b200.JPG

Following some googled info, I could recovery to apparent “normality” by  power off,  lift cover and platen up to expose the printhead, power on, closing cover quickly before printhead moved to the left rail.  Couple of times, the printer booted to its normal menu without error.  In this state I was able to print – once. The output is showing alignment errors and there was an immediate return to the B200 Error.  If I could get it to print consistently I’d at least use it until the ink ran out, but it’s not going to make it.

There are some posts from people who say they have recovered from this error.   Hard to know because it’s the Internet – but one amusing if disturbed YouTubed fix is really a video of the “final solution” approach.   There are videos that show that cleaning this part can fix the B200 error.  I’m curious,  but not enough to go down that road.  This is not a glitch, it’s a hardware failure. This printer is seven year old.

The culprit: probably the printhead.  A serious repair approach would be to replace the printhead, which is the carrier which holds the print cartridges, and easily lifts out of the carriage. This is a $30 to $50 ebay/Amazon part.  I’m tempted but this time, I’ll scrap the printer. Seven years is enough.

To make things complete, it appears that the Canon 220 and 221 printer cartridges are obsolete.  I’ve maintained a one-deep inventory of these things so I’m out about $60 or $80  in now useless cartridge inventory – about half the cost of a new printer!   ( Mar 22 2017).

Overall this printer when it worked has been the least aggravating of the home printers I’ve owned.  I’ll probably stick to a Canon Pixma inkjet.  We’ll see if the BuyMore down the street has something in stock at a reasonably competitive price to Amazon…

Alpha Plumbing

Posted in plumbing on February 16, 2017 by marksun

A pipe-organ refrain echoes darkly from the bathroom.   Wayne,  Alpha Plumbing,  feet sticking out from the bathroom cabinet, ignores the Bach Toccata in D-minor ringtone on his phone.  He is here to replace the jammed valves under the sinks and toilets and is now installing the second of eight  new cutoff valves in my townhouse.

“If this kind valve jams and you try for force um, the plastic stem going broke, and you’re dead meat.”  The valve is stuck, jammed on to the copper pipe by the original plumbers 40 years ago when my townhouse was built, and its going to take experience, tools, and brute force to get the sucker off.  Yup, that’s why he’s here.  If I tried it, good chance I would be dead meat with water dripping from the ceiling.

Most of these valves no longer turned, or dripped if you did move them.   This made working on the house plumbing a dicey business for me. The last straw was the handle breaking off the upstairs lavatory sink faucet.  The main cutoff under the kitchen sink, the cutoff to the hot water heater, the upstairs faucet valves were frozen.   Wayne got the main cutoff (under the kitchen sink) to move.  I didn’t want to try it, having no idea what would happen but once that one moved, it could do about a 98% cutoff, the remainder allowing an irritating drip for the rest of the plumbing, but at least allowing replacement of the valves.

What about the main valve? “She no close all the way now.  ‘az because was opened too far.  You got to open the valve, then back it off one turn, or going leak.  Lucky can at least close.  Otherwise, you’re dead meat because you gotta cut open the wall for get at ‘um, shut off the water to all these buildings and then replace the valve.”  Ok, so the main thing is that it’s not too bad for now.  No action on that one.    What about the hot water heater valve?  “How often you going change the heater? Leave ‘um.”  Wayne had a few choice words about other plumbers who in repairing the dreaded “heater set to boil” syndrome who only change the bottom element, and not the top one at the same time.  “idiots!”

“You put oil on this valve?”    I said “yeah,” quoting the two who recommended WD40 to loosen the valves.   Snorting  sound comes from under the sink.  “Oil no work.”  “What you can do for maintain the valve then?” I ask.   “Nothing.  Open the valve, but then close down one turn and leave um.”   I make a note of that.  “No can eat oil…”  Extrapolating quicky, you really don’t want WD40 leaching into the drinking water.  “But not going work anyway. ”    I’m  hoping that the oil has not penetrated to the actual water flow.

I mention that I’m going to replace the faucet.  “You know get one gasket come with the faucet right?”   Yes.  “Throw ‘um away and use plumbers putty under the faucet.   The gasket going rot, and then she going leak.  You not going know, and the water going rot through the particle board and you going be dead meat.”   I make a note of that.   Later on I did replace the faucet, which to make a long story short, I now wonder why I did it instead of getting Wayne to do it while he was here. One of the plastic nuts came off easily.  The other one was frozen on by corrosion and I ended up using a Dremel to cut the nut to release it, then a hammer and chisel to get it to rotate and eventually come off.  The new one, I seated on a fat seal of plumbers putty… we’ll see how that holds up.

So for the record, new valves in the plumbing.

Other advice. “If they cut off all the water to the units, open the shower first and let um run.  Otherwise the stuff in the water going clog in your sink or toilet.”  Then long story about using bread to stop a pipe to allow soldering, and the $8000 rag that some dummy plumber used to stop a pipe then soldered into the works.  Interesting side notes on plumbing on Molokai and Lanai, and his first plane ride to Hilo in 1984, encounter with turbulence and bloody mary’s.

The next crisis I expect will be the hot water heater.  I going call Wayne, not Sears on that one.

dremel care – cutting guide

Posted in note to self, tools, Uncategorized with tags on January 27, 2017 by marksun

Note to self – I use a dremel all the time but have done a not so good job of taking care of it.  I mostly use a variable chuck – very convenient –  fits 1/32 all the way up to 1/8″ – I recommend it but there’s a downside.  The collets are forgotten and the plastic nut that goes over the tool nose is long lost.   Today I  used the dremel cutting guide to cut a recess into a wood panel.   The guide requires using a collet and the chuck had to come off.   Which brings me to care of the tool.

This is a note to self for the dremel on stuff I don’t know or had forgotten.   The dremel shaft is hollow, the collet should drop or be easily pushed in all the way to the chuck.  It should come out easily.  If the collet doesn’t drop in easily, there is probably dirt, grime, or rust, all of which you want to get rid of immediately.  As you know rust will ruin the tool – useless once the collet is rusted in and will not come out.  #1 son has a couple of dremels like that.  So that dremel chuck shaft needs to be kept clean, and protected with a light machine oil or corrosion block.

The collet shaft is inserted into the dremel shaft and drops all the way down to the chuck with its four thin slots which provide the clearance to allow it to be tightened down.  The collet nut fits over it.  The bit can be inserted with the nut on or off.  The collet should remove easily and be maintained.

The collet nut fit over the collet and shaft and screws in.  It too must slide easily without binding.  Better to grease it than to have rust.  I used corrosion block to clean up and protect collets, nut and dremel shaft.

There are four collet sizes.  We use 1/8 the most for biggest bits.  Although I use the chuck most of the time, the collet system is nice and we’ll be using it periodically to keep everything in good order.

Found the manual in my drill tool box.  It shows how to use the cutting guide.  The cutting guide is easy to use but I had to see a you tube video for a picture of how its used.  Typical,  I thought I know everything I needed to know about the dremel but I don’t. Anyway, that guide allows fairly precise cutting to an exact depth.   The manual give enough information – would have saved me some time .
