Do the calibration for the scanner.

1. Place letter- or A4-size paper in tray 1, and adjust the side guides.
2. On the control-panel Home screen, scroll to and touch Administration.
3. Touch Troubleshooting.
4. Touch Calibrate Scanner.
5. Touch Calibrate to print the first pass of the calibration target(Print out).
6. Place the first pass of the calibration target face-down in tray 1 so that the arrows are facing into the MFP.
7. Touch Start to print the second pass.
8. Place the calibration target face-up into the ADF, and adjust the side guides.
9. After the calibration target has passed through the ADF once, reposition it face down in the ADF and touch Start.
10. Place the calibration target face-down on the scanner glass, touch Start, and scan the page.
After this pass, the calibration is complete.
Calibration will fails if print quality is not good...ensure that print quality must be in order..
Once calibration successfully done, restart printer several times & verify start button light, if its green every time 'u' re success. if not cleaning required for CCD which is major work & not suggestable..

Examine the full paper path of the ADF. Look underneath as well. Could be something as simple as a staple caught deep inside.

Make sure you reconnected all of the cables when you replaced the scanner. Unplug and reseat the connectors -- maybe one of them is not seated all the way in.

Hp laserjet 4345 mfp cannot photocopy anything because the startup button has a red light

Hi Bridgette.

The red light on the startup-button indicates that the machine is not ready for a photocopy. Usally there is something stuck in automated document feeder (ADF). Take a close look and see if can see something in the paperpath. If no luck, try pushing a A4 sheet manually through the ADF and see if something comes out with the sheet. Usally there is a small piece of paper, a paper clip or a staple stuck in the ADF. If nothing found in the ADF, the Scanner Controller Board is probably broke, and needs to be replaced. Good luck.

LaserJet 4730mfp - does not print anything at all - scans to email fine, goes through the motions of printing but paper comes out completely white. does not copy either. all cartridges are fine no jams and...

Is this printer new? If so make sure the little plastic tabs are pulled off of the ink cartridges Located at the bottom covering the jets. This will stop the printing. Hope this helps Merry Christmas and happy new year.
