How do i repair: hp Photosmart C7280 Printer ink system failure error: Oxc18a0101


Try holding down the ok -- cancel -- black -- color buttons with 4 fingers while at the same time powering the unit off. Keep them held down till it is off. Then turn it back on normally & it should try to do "Maintenance" & you hear a whirling noise --- that is the ink pump spinning to try & pump in ink to the print head.
Here are the details. Got the Ink System Failure message. The error code shows was '0xc18a0005'. The tech had me press and hold the '*' key on the key pad, then press the '#' key and release them both. Then he had me enter '123' to enter maintenance mode. He then had me press the right arrow (beside the OK button) until System Config. menu appeared on panel. Then pressed OK two times to clear the error condition, then cancel two or three times to return to the top menu. Then powered off and back on, printed a test page just fine, copied a document fine.

Ciss ink won't work on hp c7280


Must use included HP "starter ink" cartridges before the CISS can work. There's a 3-button sequence [OK-Cancel-Black Button] sequence when powering on that will reset the printer and bypass the "starter ink" wall you're hitting

HP C6280 says out of black ink


Something is wrong with your Blach carrier or connections. Use a bit of alcohol and clean the array of gold contacts where the Ink cartridge plugs in. Most of the pins are shutter and piezo control (get the ink on paper) but a few do other stuff like check ink level, # of hours runtime, etc. This is very common problem with inkjet printers. Hope this helps.
Also... rub the contacts on the printhead with a pencil eraser to make them shiny and bright.

Cheers!

0% color ink


We cannot bypass the color ink check, since the all-in-one uses little amount of even the color ink to print in black. Once check the expiry date of the color cartridge and clean the copper contacts of the cartridge and reinsert it again and then try to print. If the issue still persists replace the color cartridge and check for the result, if we experience the same issue even after replacing the color cartridge then the issue is with the all-in-one.

Ink Level


The obvious solution is to buy Canon ink cartridges. If you don't care about an accurate readout, buy cheaper cartridges and swap the chips. I'd suggest keeping spares on hand and change them when one color stops printing.

How do I reset the ink levels?


Well, theres the problem. Most printers can remember up to three cartridges. That includes color & black. The best way to put it is that each cartridge has a"funger print" that the printer can read, and estimated ink levels can be gaged. There is a way to "reset" the cartridges, but i do not have the document on me. Please email steve@nicesites.org and I'll send it today. I'm not saying it will work 100%, as the reset method is geared for the 56/57/58, but who knows right?
