No poweraftereplaced the adf scanner in hp color laserjet 4730mfp

Flatbed scanner is bad replace whole top half p/n q6502-60116 approx. $150 - $200

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.

the adf might be faulty and needs to be replaced, let a technician assess it onsite.

there a small pieces of paper in the paper path of the ADF by the paper jam sensor.

Please try to use scanner glass and see the resultSecondly try to scaan to PDF for multiple files.If the issue still persists clean the rollers on the ADF and if not working, replace the ADF

Hi,
I think that ADF of the printer is causing the issue and requires cleaning. Fortunately, HP Official support has provided the details along with pictures about maintenance/ cleaning of the ADF Unit.

Please visit the above link and follow the procedure to perform regular maintenance of the copier.


Hope it helps! Good Luck! Thanks for using Fixya!

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..

Remove and re-insert the cable connected to the touch screen and also try to calibrate the touch screen. The panel can be removed with ease. If not the touch panel needs to be replaced.
DO NOT FORGET TO RATE THE SOLUTION

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

Re: copy/send error....if it is not a scanner issue, do you have a problem with starting up/initializing error.... if so, it may be the hard disk failure - consider replacing it with a 40 or 80gb sata drive - may need to do nothing more complicated than replace the diskdrive which is mounted on the formatter card, which is retrievable out the back. The card is the metal faced plate on which the network/usb plug is mounted.
