Diagnosing Printer Problems
You can diagnose some problems by checking the printer’s control panel lights, as
described below, or running a printer check, as described on page 29.
Checking the Control Panel Lights
Follow the guidelines below when you check the control panel lights.
P is on The Ppower light is on when the printer is ready to print. It flashes
when the printer is receiving a print job, charging ink, or cleaning the
print head.
b
is on When the
b
error light is on, paper is out or loaded incorrectly, or you
have a paper jam. If necessary, load or reload paper and press the
b
maintenance button. If paper is jammed, press the
b
maintenance
button to try to clear the jam. If that doesn’t work, turn off the printer
and gently pull out all the paper. Turn on the printer and press the
b
maintenance button to resume printing.
When the
b
error light is on and your paper is loaded correctly and not
jammed, you need to replace an ink cartridge. Determine which
cartridge is out of ink and replace the cartridge as described on page 21
and page 22.
b
flashes When the
b
error light flashes, your ink supply is low. Determine
which cartridge is low as described on page 22 and make sure you
have a replacement cartridge.
P is off
and
b
is on
When the Ppower light is off and the b
error light is on, jammed
paper may be blocking movement of the print head. Turn off the
printer, open the cover, and check inside for any jammed paper. Then
turn the printer back on. If the lights are still in the same state, contact
your dealer or EPSON; see page 37 for contact information.
