Cartridge error


The problem could be due to a communication failure between one of the printheads (cartridges) and the All-In One (AIO) or by a short in one if the printheads. Please follow the steps below to identify and fix cartridge issues:

1. Make sure the printer is on.
2. Open the printer cover. The print cartridge carrier moves and stops at the loading position, unless the All-In-One is busy. Note: If the carrier does not automatically move to the center, turn off the printer or unplug the printer from the power source and then carefully slide the carrier to the center.
3. Remove both cartridges from the carrier.
4. Close the printer cover.
5. Re-brick your printer by pulling out the power supply - black box behind the printer where the power cord is plugged in to, and re-plug after 30 seconds.
6. When the printer turns on, reinsert one cartridge first. Close the printer cover and check for any errors.
7. If no error appears, reinsert the other cartridge. Close the printer cover.
8. Replace whichever cartridge is causing the error to appear with a new genuine cartridge. Try to print a document again to verify that the problem is fixed.

In hp officejet pro k5400 printer i can't get color print after giving any print...i've installed new ink cartridge also but still i can't get color print....


Try Cleaning the Cartridges manually and automatically.
For the cartridge clean it with a damp lint free cloth and also for the printheads wher eyour gonna be inserting the cartridges.
Follow these steps do do the automatic aligning and cleaning:
Click Start and then go to Printers and Faxes (XP), Printers(Vista), Devices and Printers(Win 7)
1. Right Click on your printer Icon 2. Go to Printing Preferences 3. Click the Features Tab 4. At the bottom of the window you will see Printer Services or Device Services. Click on it. 5. Choose Align Printheads on the list.

For Cleaning the Printheads, Instead of choosing Align Printer choose Clean Printheads.
I hope this helped.
Try Printing Again. I hope I was able to solve your problem. :)

My printer stood unused for about 8 months. Then


Remove all the cartridges from the printer and check for expiration date on the cartridges, if the cartridges are expired, you need to replace them with HP genuine, use of refilled one's cause many issues.The cartridge that is compatible with this printer is HP 14 black and HP 14 tricolor.
To align the printheads at any other time:
  1. Press Menu .
  2. Press 7 , then 3 . (For the HP Officejet D 125xi press 3 , then 3 again)A page prints to confirm printhead alignment.

Dosen't reconize 8 GB SDHC memory card


Older model printers won't recognize high-density memory cards.

2 gb is probably the largest to be used in your printer.

HP D135 - replaced printhead - still doesn't print in that color


try this link : I followed the directions and fixed the problem. the instructions that came with the new printhead weren't really complete.

Here's essentially all I did for my fix - Opened the printer top, turned the printer off. Removed the "bad" printhead, cleaned the metal contacts on the printhead and printer with windex. Closed the printer. Turned it on. waited for it to reset. Opened the printer. Turned the printer off again. Installed the printhead. Closed the lid. Plugged the printer in again. When it was ready I accessed the HP toolbox and alligned the printheads and cleaned the printheads. It worked. Here's a link with photos.

Kodak ESP-3 Will not print calibration page. It goes thru the motions, spits out blank paper. This is supposed to happen prior to connecting to computer or installing software. Tried two printheads


I have severe and often different problems with my Kodak ESP-3 printer. Sometime it`s banding of the colors, then I`ll align the printhead and I`ll have a color problem or no color at all. I just talked to Kodak Customer Service by phone, 11 a.m. PST. After a few automated questions I had a live operator in less than 3 minutes. The service tech went thru some diagnostic steps with me and the printer and after about the 5th step determined I had a faulty printer head. If the green on/off light keeps blinking when it shouldn`t be, that is a sure sigh of faulty printer head, it means the printer is not recognizing the head. Kodak seems to be very aware of this problem and are sending me a new printer head UPS, free of charge. After reading some previous reviews I`m suprised how good the customer service was. Maybe I just called at the right time and got lucky.
