How to Troubleshoot Blank Pages on an HP 4600 Printer

Check the display for an error message. If the display reads 'Clearing paper from printer,' the engine has detected a jam and is attempting to eject the jammed pages automatically. These pages will often be blank.
Check the display for 'Performing PRINT/STOP TEST' or 'Performing SERVICE TEST.' Either of these messages indicates that the printer is going through a test procedure that may eject blank pages.
Reduce the amount of paper in the input tray if the printer is feeding multiple blank sheets at a time. The printer will pull extra pages through if the input tray is overfilled.
Replace the paper in the input tray with the correct size if needed. If the 4600 printer detects the paper as an incorrect size for the print job, it may eject the paper without printing anything on it.
Replace the ink cartridges if certain colors are blank on the page. Replace the black cartridge if printing a black text document that is coming out blank. The printer may attempt to print even if the ink level is low or empty, but will unable to print anything on the page, causing it to come out blank.
Remove the sealing tape from newly installed cartridges. The tape covers the print heads and should be removed before installing the cartridges. If the tape is left on, it will prevent ink from getting on the pages as they print.
Press the 'Check mark' button on the control panel to enter the printer menu. Run a diagnostic so the printer can attempt to determine the cause of the blank pages printing. Press the up or down arrow to select 'Diagnostics.' Press the 'Check mark' button. Press the 'Down' arrow to highlight 'PQ Troubleshooting.' Press the 'Check mark' button. The printer runs a diagnostic and returns to a ready state when done.
