Solving Paper Problems
If paper feed or paper jam problems occur frequently, try one or more of the 
following solutions:
For roll paper, try adjusting the Paper Suction setting. See page 81 for 
more information. You can also adjust this setting through your printer 
driver.
For heavy or thick media, follow the instructions on page 74 to load the 
media correctly.
Make sure the paper is not folded, wrinkled, or damp.
Make sure the printer’s environment falls within the required 
temperature and humidity range.
Make sure the paper is not too thick or too thin. See page 55, page 191, 
and page 194 for paper specifications.
Make sure no foreign objects are inside the paper path.
Make sure the printer isn’t located in a brightly lit area. The paper 
sensors may not operate correctly.
Make sure the Media Type and Paper Source settings in the printer 
software are correct.
Make sure the PLATEN GAP setting is correct for the paper or media 
you’re printing on. See page 75 for more information.
If you’re not using Epson media, use a paper configuration to adjust for 
the paper’s thickness and drying time; see page 94 (for Mac OS X) or 
page 125 (for Windows).

Fixing Paper Eject Problems
If the paper is curled too tightly to eject properly, make sure the paper guides 
are attached to the printer. There are two paper guides for the Epson Stylus 
Pro 7890 and five for the Pro 9890.
Attach the guides to the bottom of the printer as shown:
Do one of the following:
If you are feeding paper in front of the printer, 
move the guides to the forward position.
If you are feeding paper backward (under the 
printer), gently squeeze the paper guides and 
push them to the backward position, as shown 
below:

Solving Problems With the Optional Auto 
Take-Up Reel
If you have problems using the optional Auto Take-Up Reel, try these 
solutions:
Make sure you turned the printer off and then on again after installing 
the Auto Take-Up Reel, and that the cable is securely connected to both 
the printer and Auto Take-Up Reel.
Make sure the Auto switch is set for the direction in which you loaded 
the paper to be taken up. See page 203 for details.
Make sure you pressed the printer’s lPaper Source button to select 
(Auto Cut Off).
If the Sensor light flashes slowly when you are not printing, the sensor 
may be misaligned or there may be an obstacle in the sensor’s beam. 
Make sure nothing is impeding the sensor’s beam.
If the Sensor light is off, the Auto Take-Up Reel may be turned off or 
the sensor cables may be disconnected. See the installation instructions 
included with the Auto Take-Up Reel.

Clearing Stored Print Information
Your Epson printer stores various print information for the last 10 jobs 
printed, such as print job name, computer name, date, time, number of
