Hi,

The HP88 black cartridge contains is a pigment ink type which I've found from painful experience has just not been tested properly by HP for use with this printhead.

The problem will not be the cartridge but most likely the printhead which will have clogged due to heat, lack of humidity, etc..

The best solution I've found to date is to purchase a new printhead and find a 3rd party ink supplier with dyebase black ink instead of the pigment type. The printhead is much less likely to clog and can cope with a wider range of temperatures and environments compared to the original black.

I hasten to add this is based on my experience in four primary schools and from three printers at home all of which use the HP88 cartridge... Warm and dry environments just stop this printhead after a short period of time whereas cool, humid spaces seem to keep the printers working much longer.

Hope this helps.

5C00 Error Code as well as yellow and green alternating lights


To fix this error is much easier than it looks. Unplug the printer power. Move the ink cartridge cradle to the left. Over to the right you will see a small pad about 1cm square. This pad and the area around should be covered with ink. Get a cloth and press down on this pad - it's not fixed so should come away with the cloth, otherwise use tweezers gently. Squeeze the pad several times between your thumb and forefinger while inside the microfibre cloth to remove ink build up. Then when not much ink comes out on the cloth, clean the area in the printer around the pad so that looks free from ink too. Then position the pad back in place, move the cradle back into position, plug in and switch on - should work fine now.

My Epson WF-3640 is printing with gaps in the text. How do I fix this issue?


Make sure you should remove shipping tape from the ink cartridge. These taps are used to protect printer during shipping but you have to remove it before starting printing. Beacuse these taps prevent the ink to entering in print head. If you will not found shipping tape in your printer then there is terr off strip, remove it. The tear off strip seals the the vent holes on the top of the cartridge to prevent it from drying out on the shelf or during shipping.
After ensuring that the shipping tape has been removed, run the printer's "Head Cleaning" utility to prime the cartridge, then print a test page.

How to clean ink absorber for canon mp237


First of all open the ink cartridge of your printer.
When the ink cartridge would move all the way over, then disconnect the power cord of your printer.
Now pull the frame of rubber from the printer and remove ink pads.
To clean ink pads you may place them in a bowl having warm water and start rubbing and squeezing them to clean it from ink.
After removal of ink, keep the pads separate for dry.
When the pads get dry completely, place them back in rubber frame.
Reinstall the rubber frame in your printer.

Printer won't recognize cartridge


I had the same problem. I'm not sure but I think I replaced the cartridges when the printer was on because I turned the printer off and removed one of the cartridges. When I turned the printer back on it recognized that cartridge but not the others. I turned the printer off again, rmoved all cartiridges and put them back in when the printer was still off. When I turned the printer on again I had no problems. So...try turning off the printer, rmove all cartridges, then put them back in and restart printer. Hope this works for you .
