scanner and copy outputs have vertical lines on right side of page top to bottom officejet pro 7740

[JRR45]

my officejet pro 7740 suddenly started not scanning and copying.  Scans and copy oututs have vertical lines on right half of page running top to bottom.  What is the cause of this and how can it be corrected?

Welcome to the HP Support Community.

Does this from the scanner glass or the Automatic Document Feeder or both?

Reset the printer to clear certain error states by calibrating the copier mechanism, and then check the power source to confirm the printer is getting enough power to operate the copier.

1. Press the Power button to turn on the printer, if it is not already on.

2. With the printer turned on, disconnect the power cord from the printer.

3. Disconnect the power cord from the power source, and then wait 60 seconds.

4. If you previously connected the power cord to a power strip or multi-plug outlet adapter, reconnect the cord directly to a wall outlet to ensure the printer is getting enough power.

5. Reconnect the power cord to the rear of the printer, and then turn on the printer.

6. If you have an HP DeskJet 3700 series printer, calibrate the scanner after resetting the printer.

7. Load the original document or photo, and then start a copy job.

   • If the issue persists, connect the printer power cord to a different wall outlet to determine if the original outlet is causing the issue.

If the issue persists, please perform the remaining steps from this document: https://support.hp.com/in-en/product/hp-officejet-pro-7740-wide-format-all-in-one-printer-series/768...
