I get an inquiry about my Canon Selphy from a close one who wants to fix it to use it. I last touched it several months ago.
The same day, I go to a friend’s website and it has buttons linking to their friends. In the blog of one of them, one of the recent entries is https://lisanne.gay/pages/Canon Selphy CP760 repair/
I find and screw back in the four screws into the deep holes on the bottom of the CP530. I find the separate transparent box where I put the spare cartridges and paper caddy. I find the box with the CP510, loaded with way more manuals and packs of paper. I put the CP510 power supply into it too for transport. I put the CP530 in its own box.
I find the cartridges inscribed with white marker by myself. The inscriptions are “came w/ 1st”, “came in 2nd”, “second w/ 2nd”. Of the two models, one came in first into my possession and this is what that refers to — which cartridge came inside which one or along with which one.
I remember one of the printers I managed to print with images that were blank on almost half of the picture, with the line only very slightly irregular. I remember checking it for the broken lever — it didn’t seem to be the case.
I think one of the repair videos with the broken lever I watched was Canon Selphy CP510 Repair by TechBench. I think I recognize the dog printed. Now I read from anne that they didn’t see the crack. Maybe I didn’t inspect with my finger either.
I remember another kept reporting low ink no matter which cartridge I gave her, with the ones working alright in the other.
I remember I had to tweak something in printing settings to make the CUPS driver print without margins. I download the “lever not fixed” photo from anne. I install the driver (the name is arranged a bit differently in the driver name, but model is the same). I try to print the photo, and look into “Advanced”.
- I find “Use legacy dyesub gamma curve” — I remember it looking alright either way.
- I find “Linear Contrast Adjustment” — I remember it doing something cool.
- I find “Borderless” — I’m pretty sure that was the one.
I click OK and click Print. The job results in an error: “Incorrect paper loaded (01 vs 11), aborting job!”. The caddy says “Postcard 100×148mm/4×6inch Size”. I try again with the other, gray-tinted paper caddy, same error. I try again, see this exact size preselected, so I proceed again, same error.
A SourceForge discussion from 2013 describes this happening after an update. It links to “Building modern Gutenprint on a Raspberry Pi” by Solomon Peachy. The blog post also links to CUPS has options where one may find all kinds of settings for print image manipulation including disabling the border margins. It turns out Libreoffice Writer doesn’t enter smart quotes when adding them in the Text field of the Hyperlink tool.
Last time it worked, it was an openSUSE Slowroll. Now it’s a Ubuntu.
One PPA I added earlier doesn’t supply an InRelease file for my release. That is one of the reasons of error of the graphical auto-updater. Several broken graphical updater windows later, and seeing the updater successfully show the available updates after the intervention, I hope to not be prevented from using apt. I get shown an error once more in the graphical updater. I’m getting asked if I want to end Notifications of the Discoverer (per translation). I still can’t use apt. I realize I left the sudo su earlier. — I follow the instructions from Peachy’s blog post, reordering the commands to skip the apt remove at first, and not running the build in sudo. I run ./configure without the suggested options (why would I not want documentation and why should a regular user build the debug symbols). The ./configure tells me to make clean first; I don’t. Compiling takes 4 minutes (…without the -j4.) I make install, remember I was supposed to remove the apt packages, then make install again.
I try printing again. It throws “Backend /usr/lib/cups/backend/gutenprint53+usb does not exist!” at me. I add a duplicate printer as detected anew: “Incorrect ribbon loaded (03 vs 01), aborting job!”
I figure I will swap out the “Second [came] w[ith] 2nd” ribbon for a “Came w[ith] 1st” one. It works. It printed the left half (the cable connectors side).
It seems we figured out that back then first I bought the CP530, then the CP510. The CP510 was bought also because a lot of paper packs came along, I think.
It looks like it made the cuts somehow of the margins (it didn’t, I figured later). I choose to put it in reverse into the caddy regardless. In Properties > Advanced, I have to switch to Borderless again. I go back, remembering the rotating solution was quite simple — I press Ctrl+R Ctrl+R, and go into print dialog again. In Properties > Advanced, I have to switch to Borderless again. The result of two-take print is misaligned by about a millimeter — perhaps there was a split-second jam from the broken-off margin — it hit cables in the back, that’s why, I think. The over-print is rather thin, but the artifacts are black and a bit disturbing this time, and it shines under the light differently; the photo was somewhat dark.
I take something to eat. When I’m done discussing a sidetrack and back, my laptop seems to be somewhat frozen up. I take the time to ask partner if I should get started with the disassembly now or are we going soon. Negative answer prompts me to think of to-dos to wrap up with:
- Inspect the lever in CP530 by touch
- Try CP510 with the “Second w/ 2nd” ribbon cartridge not hoping for anything
The laptop froze irrecoverably. I press the power button long. LibreOffice Writer recovers me everything once I’m back in. That’s it in this matter for the day.
