The printer can not align cartridges.

What is the black cartridge version that you are using on your Lexmark X125 printer? If you are inserting a photo cartridge on your printer, please follow these steps: 1. Remove the black cartridge and insert the photo cartridge. The printer LCD screen will display CARTRIDGE? NONE CHANGED. 2. Press the Options button to select NEW RIGHT and then press Start. The printer LCD screen will now display RIGHT CARTRIDGE? 3. Use the Options button to select the STD PHOTO cartridge type and click Start. An Alignment page will then print. When the Alignment page is fully printed, the LCD screen will display CARTRIDGE ALIGN. 15 [00-30] A , where - 15 represents the straightest line on the page; - [00-30] is the value range you can select from, between 00 and 30 - A represents the line in each section. 4. Use the numbers on the keypad to select the number of the line you think is the straightest. As you press the number, the LCD will change to the next line automatically. Select the number representing the straightest line in each section.

I had the same problem so I did this Press and hold the Enter button, and then press Setup . and now my printer works :)

To align the cartridge from the control panel:

Please follow the steps given below:

1. Please Load a plain paper.
2. Press and hold the "Scan" button for three seconds.
3. An alignment page prints.
4. Place the alignment page onto the scanner glass.
5. Press the "Scan" button.
6. Once scanning is complete, the cartridge has been aligned for optimal print quality. Alignment must be complete before continuing with any print jobs.

I just had the same issue (align page not detected).

We had just re-installed the empty color cartridge back into the printer (long story but basically we knew we could only print B/W).

The align page printout had a lot of empty spaces around the black lines. This is apparently where the color lines are supposed to print.

Without those color lines, the printer would not detect the align page as color is part of the alignment being done.

Since we only wanted black printouts, I pressed 'cancel' to stop the alignment process, and now we just hit the Black copy button and ignore the alignment prompt on the printer window.

The HP site (enter psc750 in product window) has some helpful ideas as to what the problem might also be. It could be the shipping tape is still on the new cartridge (and preventing the black or color from printing on the align sheets) etc.

Printer keeps trying to perform an alignment after installing a new black ink cartridge fix:

1. Unplug USB
2. Turn printer off
3. Wait 10 seconds
4. Remove paper from paper tray so printer has no paper to print on
5. Turn printer on
6. Printer messages to insert paper in paper tray
7. Press and hold “Setup” and “ Cancel” buttons and press “OK”
8. Should be good until next black ink cartridge change.

You can also bypass the alignment. When the message for alignment displays on the display => Press Setup and Options (or Copy Options ) simaltanious.The last known alignment is used when the alignment is bypassed.
