Correcting Plates
You can delete images with IWATSU Elotax Corrector OX-1. You can also use AGFA Lithostar
Copyrapid Correction Pen. Also, a pencil eraser works well to delete a small section from an image.
Reusing Plates
Epson DirectPlate Aluminum plates can be reused if you would like to store them for use again to reprint
the job.
If you plan to reuse a plate:
1. Remove ink from it by printing 20 to 30 impressions after disengaging the ink rollers from the plate.
2. Wash the plate with water before removal from the press.
Gumming or other special treatment is not required for reusing the plate. Store the plates in a dry, cool
place.
Washing the Press
The following press washes are recommended (not carried by Epson):
• Varn EC Wash
• Ultrachem Prima Wash
• Varn News 75 Wash
• printcom ® wash 202B
• Sun Chemicals SUN WASH U H8830A
Note:
Test washes by rubbing a little on a plate to see if it removes the image.
Maintenance
• See the Epson Stylus Pro 7900/9900 Printer Guide for printer maintenance.
• Keep the PCU trays clean to retain their low-friction properties. Make sure the PCU is turned off.
Every week, wipe the trays with a paper towel moistened with a non-abrasive glass cleaner. You might
notice a light gray deposit of dust on the towel; this is normal. Do not spray glass cleaner directly on
the trays or the PCU.
