HP920c cartridge light wont stop blinking, printer wont print

Please refer below for detailed troubleshooting of the specific condition:

PRINT CARTRIDGE light RESUME light POWER light Blinking Off On c00106873.jpg c00106862.jpg c00106865.jpg Problem

The printer top cover is open, or there may be something wrong with the print cartridge.


  1. Close the printer top cover.
  2. If the PRINT CARTRIDGE light continues to blink, continue with the following steps:
    1. Open the top cover. The print cartridge cradle will move and then stop.
    2. Locate the yellow arrow on the top of the print cartridge cradle. The yellow arrow points to a drawing of a cartridge that represents a symptom. Perform the task associated with that symptom.
    3. For a list of symptoms, refer to How to use the cartridge drawings under the top access door on a 900 series Deskjet .

I just experienced this with my 920c. I cleaned the contacts in the cartridge holders with alcohol and the problem went away.

Amber light!

Clean the contacts in the cartridge holder (Iso alcohol & cotton swab work well).

I've just installed my HP deskjet 920c printer, but the amber light seems to not stop blinking. I've installed only the black ink (c6615d) 'cause I have no use for the color ink.

You can't operate the printer without the color cartridge, even if you don't need it. You can always keep an empty one in, but you must have both in.

Hp deskjet 842c blinking ink cartridge light

You have to take off the clear strip of plastic over the copper area, or the printer will not detect it. There should be a green pull-tab on the cartridge.

Either you have ran out of an ink, because some epsons wont run until you replace cartridge, you have a document pending a print, or you need to disconnect printer, uninstall drivers from Add/emove programmes. Re-install driver then re connect printer when prompted
