There are several reasons why the HP All-in-One may fail to align the cartridges. The most common reason is an ink cartridge that has one of the following problems:
One of the ink cartridges is low or out of ink. Black and all three colors must be available.
The paper has already been printed on or is colored paper.
Protective tape on a new ink cartridge has not been removed.
Contacts on the ink cartridge are not meeting the contacts in the carriage correctly.
Cartridge is remanufactured or refilled. Refilled or remanufactured ink cartridges may have been damaged during the refilling process or have clogged ink nozzles.
The ink cartridge is defective.
Follow the steps below to resolve the problem:
Step one: Examine the paper the alignment page was printed on
The alignment page must be printed on clean plain paper of either letter or A4-size and that has a brightness level (as printed on the paper package) of at least 85. Colored papers or paper that already has printing on it will cause the alignment to fail.
Step two: Does the alignment page print correctly
On the HP PSC 900 series, if the page ejects immediately or a "Paper mismatch" or "Paper too narrow" message appears, the 4 x 6 paper tray
selector located on the paper output tray is pushed forward. Move the selector all the way back toward the front on the HP All-in-One.
Look at the alignment pages that have printed. Compare the alignment page to those included in the " images of alignment pages " section at the bottom of this document.
If any of the colors or the black is missing, faded, or streaked on the alignment page, there is a ink cartridge problem. Click here (buu02176) (in English) to learn how to correct ink cartridge related problems.
Step three: Perform a ink cartridge cleaning
The ink cartridge cleaning process can be performed even with the alignment message showing in the display. Follow the steps below to perform an ink cartridge cleaning process from the front panel:
On the front panel, press Menu or Setup (depending on the model).
Press the Right Arrow (>) until Maintenance or Tools appears, and then press the Enter or OK .
Clean ink Cartridges should appear in the display. Press Enter or OK to begin the cartridge cleaning process.
A page will be printed during the cleaning process with all of the colors on it. If any of the colors or the black are missing, faded, or streaked on the alignment page, there is a ink cartridge problem.
Step four: Try to align the page again HP products
have two methods for aligning the ink cartridges, fully-automatic and semi-automatic. The steps are different for each type. Refer to the information below to determine which alignment method your product uses.
Automatic - these products use a sensor to check the alignment page as it is printed. You are not required to take any action to complete the alignment process. Click here if your model does not print an instruction page.
Semi-automatic - these products print the alignment page and instructions for scanning the alignment page using the scanner assembly. Click here if your model prints an instruction page .
Automatic cartridge alignment
Perform the following steps to align the ink cartridges:
Disconnect the power cord from the unit, wait five seconds, and then plug it back in. This will reinitialize the unit.
Print another alignment test page. If the Press Enter to align message is not currently on the front panel display, complete the following steps to print an alignment page:
Press Setup or Menu on the front panel (depending on the model).
Press the Right Arrow (>) until Maintenance or Tools appears in the display, and then press Enter or OK (depending on the model).
Press the Right Arrow (>) until Align ink Cartridges appears in the display, and then press Enter or OK (depending on the model).
To determine if the automatic alignment is functioning correctly, look into the output tray as the alignment page is printing; a blue light
should be visible periodically on the page as the cartridges move back and forth. If this light is not present, the unit will not be able to align the cartridges and will require service.
If the blue light is visible and the alignment pages are printing correctly, but the alignment pages still fails, there still may be a hardware problem with the unit.
If there are no other printing problems and you wish to continue, use the information in the " Bypassing the ink cartridge alignment " section below to bypass the alignment. The information from last successful alignment will be used.
If the message keeps reappearing or other print quality problems occur, service the product.
Models with a semi-automatic ink cartridge alignment
Some HP products have a semi-automatic alignment process. These models do not have an additional sensor and will print two pages for the alignment process instead of one. The alignment page must be placed on the scanner glass or into the automatic document feeder
(HP Officejet V series) and scanned.
Disconnect the power cord, wait five seconds, and then plug it back in. This will reinitialize the unit and force the scanner to calibrate again.
