Cleaning the rollers:
=============
1. Unplug the printer power cord and remove the back door.
2. Wipe the paper rollers with a lint-free cloth lightly moistened with distilled or bottled water. Rotate the rollers with your fingers to clean all the way around.
3. Allow the rollers to dry completely, then close the rear door.
4. Open the print carriage access door.
5. Use a soft cotton swab dampened with water to clean the four small metal paper rollers. Avoid touching the encoder strip. The illustration below shows the relative locations of these parts.
6. Use a clean, dry cotton cloth to wipe the carriage rod. Move the carriage as needed to clean the full length of the rod. Do not lubricate the rod.
7. Close the printer, plug the power cord in, and turn on the printer power.
8. If the error message does not go away, you need to get the printer serviced.
Power Cycle:
========
Follow the steps below to power cycle your all-in-one:
1. Verify that the unit is switched on. Disconnect the USB/Ethernet cable from the All-in-One and also disconnect power cable from All-in-One and also from wall outlet.
2. Wait 30 seconds.
3. Plug in the power cable to All-in-One and also to wall outlet.
4. Check for the functionality.
Connect directely to wall out let:
======================
The surge protector may not supply sufficient power to the printer. To isolate the issue please remove the power plug of the printer from the surge protector and connect it to the wall jack directly.
Being a All-in-One Machine it needs full voltage to be supplied while initializing Surge protectors supply suppressed voltage to the printer which leads to unexpected issues in the printer
Semifull Reset:
==========
Note:
A semi-full reset will do the following:
The user settings to the factory defaults, Language and country settings on some models, Fax logs, Fax headers, Fax speed dial information.
Reset the All-in-One to the factory default settings by using these instructions:
1. Unplug the power cable from printer when the printer is powered on and wait for 20 seconds.
2. Then, press and hold # and 6 while plugging in the power cord.
Continue holding until it displays Semi Full Reset message in the front panel of the All-in-One.
