Open HP Toolbox on your computer and look at the Status Tab. You did use fresh HP cartridges.

On my HP, you press "ok" and it then does the cartridge alignment. Then "?" is gone.

Printer is not printing yellow, Light Cyan, Cyan, blue lines through Light Magenta & Magenta, What could be causing this and it is also leaking black ink out of the bottom of printer.


Is it under warranty, are you re-filling the cartridges? If yes to first and no to the other two, send it back under warranty. If you use copy cartridges or refill old ones the warranty is vod. This means you need to replace the printer. To be honest, you'd be better off buying an Epson all in one. Even the wireless model start @ sound 40gbp and you can buy good copy cartridges from choicestationery.com

MY HP LaserJet 2840 has a brand new Toner cartridge. Now it won't print at all and we are getting a "OPC at end of life" prompt. What does this mean?


Imaging drum reach 20,000 (black only) or 5,000 (color), replace the image drum.

Supplies life
The life of the imaging drum depends on the number of black-only or color pages that print jobs
require. Imaging-drum life is also affected each time the device calibrates because calibrating causes the imaging drum to rotate. Imaging-drum life is measured in terms of number of rotations rather than number of pages printed.
The type and length of print jobs also affects drum life. A series of short print jobs uses more drum
life than an equivalent number of pages printed in a single large job. To extend drum life, print
multiple copies of a print job at one time rather than sending the same job to the device multiple times.
The life of a print cartridge depends on the amount of toner that print jobs require. When printing text at 5% coverage, black print cartridges last an average of 5,000 pages and cyan, magenta, and
yellow print cartridges last an average of 2,000 pages. High-capacity cyan, magenta, and yellow print cartridges last an average of 4,000 pages. (A typical business letter has 5% coverage.)

This model printer has only two slots for ink cartridges. One is for a black ink cartrigde and the other is for a tri-color cartridge which contains cyan, magenta and yellow inks.
This tri-color cartridge has run out of yellow ink, you need to replace this tri-color cartridge.

Is it possible to use non HP ink in ths printer? Tried using "remanufactured ink", and concluded that this printer may be programed to block the use of NON HP INK.


It is always recommended to use genuine HP cartridges.
As if we will use the non HP or refilled cartridges, it will reduce the life of the printer.
And we will get an error "cartridge problem".
Plaese use the below cartridges, which are compatible with this printer.
HP 02 Black 660 pages
HP 02 Black Twin Pack 1320 pages
HP 02 Color Combo See single 02 inks
HP 02 Cyan 400 pages

I replaced an ink cartridge because the printer stopped working and showed a message that the old cartridge is empty. However after putting the new one in but the printer still refuses to work and shows...


maybe the cartridge is wrong, release it and clean the electrical contacts, put them again one by one, if notting happen, try this
Solution As the printer operates, it moves ink from the ink cartridges into a printhead reservoir. The printer does not deliver a message when an ink cartridge goes empty, because it still has ink in the reservoir. The printer continues printing until the ink level in the reservoir falls to a first trigger point - then a message appears advising the printer owner to Replace Cartridges Soon . At this point, other cartridges that are empty but have not reached the trigger point are also mentioned in the message, to save trips to the retailer. After the first trigger point, the printer can continue printing until ink levels in the reservoir reach a second trigger point. At the second trigger point there is only enough ink left to perform vital servicing tasks, and a new message appears, saying Ink Cartridges Empty . The options offered depend on the usable inks remaining. If no options are offered, the cartridges indicated must be replaced before printing can continue. The Ink Cartridges Empty options are described in the table below: Ink colors out Option Print mode possible All Cancel None Black

AND

Cyan, Magenta, or Yellow (any or all) Black only Continue with other colors Cyan/Magenta/Yellow mode (composite black)

Text and photo quality will differ from those printed when all colors are available Light Cyan or Light Magenta (either or both) Cyan, Magenta, or Yellow (any or all)

(Black still available) Print with black ink only Grayscale

Your printer uses the following cartridges:

HP 74 - Black ink
HP 75 - Cyan, Magenta, and Yellow ink
HP 99 - Photo Black, Light Cyan, and Light Magenta

You need Photo Black, Cyan, Magenta, Yellow, Light Cyan, and Light Magenta to print photos. To accomplish this you install the HP 99 photo cartridge where your HP 74 black cartridge usually goes and you keep the HP 75 color cartridge where it's at. I don't know why your printer told you to remove both cartridges, then reinstall the HP 75 color cartridge.

Re-installing yellow cartridge in HP 2840


There is a gray button right of the LCD display that has a black arrow circling clockwise and four color dots (magenta/black/cyan/yellow). Push it until you see the "Rotating to Yellow" in the LCD display, then open up the top of the printer by pushing the big gray latch next to the picture card reader at the right front of the printer. You now have access to the cartridge. pull it out and examine it. If it is a new cartridge, check to see if you pulled the plastic dam strip out (which keeps the toner in place in shipment etc).
