Photosmart 7520 Automatic Document Feeder ADF

[ikelly]

Photosmart 7520 printer believes that paper is in the automatic document feeder and is not inserted correctly.  There is no paper in the ADF. This results in the printer being unable to scan from the flatbed glass or the ADF. The problem occured while using the flatbed scanner and constantly opening and closing the scanner lid.

The swtich sensor inside the ADF does not make the noise it used to when paper was inserted. The sensor moves but does not register the paper being loaded. The small motor that drives the gearchain to pull the paper through the ADF only runs for a second befoee the error message occurs. All rollers are cleaned as per other advise, the rest procedure was followed and the power up/down procedure was followed with no positive resolution.

I need a solution that addresses the sensor failure or a procedure to remove the ADF and replace with an alternate ADF (I have a second 7520 with a working ADF but with a very worn printer mech).

Please assist, this device is relatively new and a significant investment has been made in buying ink for it

The solution to use the photosmart pc based software for scanning will not suffice

Hi @ikelly

Welcome to HP Forums. This is a great place to get support, find answers and tips.

I understand that that your Printer keeps saying there is paper in the ADF eventhough it's empty.

I suggest you do a Printer Reset

(1) Turn the printer on, if it is not already on.
(2) Wait until the printer is idle and silent before you continue.
(3) With the printer turned on, disconnect the power cord from the rear of the printer.
(4) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

Hello @KrazyToad 

I already tried the methods you outlined and communicated that it does not work. What I need is a disassembly document that allows me to swap the ADF between a new and older printer.

Can you please help me to find a document that allows me to remove the top of the printer or the ADF?

Thank you

Hi,

as @KrazyToad is out of the office today, I'm replying to you.You've done a remarkable job performing the steps. 

I would like to inform you that the ADF is a non removable part of the printer. If there is a hardware failure with the ADF then the printer needs to be replaced.

You may contact our HP phone support team to explore the available options for the printer based on the warranty.

Hope this helps. Good luck!
