Grinding Noise just before printing from my HP Envy 7645

[FrankKeen]

Experiencing severe grinding at the gear just below the color ink cartridge just before printing first document and when the printer is shutting down. I performed the tasks suggested for clearing paper jams and I "reset" my printer by disconnecting and reconnecting the power cord with no change in the grinding. I have owned the printer for several years and this is the first issue I've had with it. I cannot see what it is grinding against and it appears that it may be inaccessible to non-HP "shade tree" mechanics.  Any suggestions would be welcomed.

Clean the paper feed and pick rollers

Gather these materials:

• Long, lint-free cotton swabs

• A clean, lint-free cloth, or any cloth that does not come apart or leave fibers

• Distilled, filtered, or bottled water (tap water might damage the printer)

Step 1: Clean the paper feed rollers

Follow these steps to clean the paper feed rollers.

1. Remove any paper in the printer before you clean the rollers.

2. Press the Power button to turn off the printer, if it is not off already.

3. Disconnect the power cord from the rear of the printer.

      WARNING: 

   You must disconnect the power cord before reaching inside the printer to avoid risk of injuries or electric shock.

4. Open the cartridge access door.
