Error Code:380 the printer is saying open side cover error code 380 but I have looked in the side taken out the paper tray and looked in there and also taken out the colour cartridges and fuser cartridge out but to no avail. Not sure what to try next.

This is a typical error code. Take a flashlight and look closely inside after removing the cartridge. There probably is a speck of paper that may be covering the sensor. Paper pieces are hard to find sometimes but be patient and look closely lifting up the registration cover assembly. Also look in the tray for a paper that may have not gone through correctly. Remove the tray and also look up in the cavity of the printer.

0xF1 means there is a paper jam.

Epson WorkForce WF 3520 All in One Printer

Check the paper alignment clip in the tray is Exactly on the right setting (A4), even if 1 setting over you will get this error

C0202= tray 1 elevator failure.
Open tray 1, check and make sure paper is loaded correctly.
With tray open, open and close front door. This will reset error code. With tray 1 open look to see if paper is stuck behind tray in back of machine, if so remove it ( this will block the lift motor for the tray).
Close tray 1, if you hear a popping noise the lift motor is damaged and will have to be replaced. Until it is replaced operate machine with tray 1 out to prevent error code.

what is the error ?
does it says Paper jam, Open the print cover and remove paper jam..

If this the error repeating then make sure,

1. u r not overfilling the paper tray
2. put the printer on a hard surface (not on a half out surface)
3. from now on be gentle with the paper tray.
4. unplug the printer everytime u r done or atleast overnight.

thanks

error [6000] or light blinking 3 times is mean there is an error occurred in the LF encoder signal.

Error 6A00 is AP position error.First, make sure there is no paper jam anywhere in the machine.. look inside, rear, where the paper tray (output)
is, etc to see if you find any shreds or torn paper that may have gotten stuck and you didn't see.Look carefully in the zone of Purge unit, using flashlight in the right side on printer.If this not help your printer need service.

check in back side of printer there should be small paper jam check it.

Ich denke es mus die Sensorplatine mit den drei Gabellichtschranken im manualtray ausgetauscht werden.
