DocuColor 40 MATERIALS USAGE GUIDE
Hints, Tips and testing Results
Xerox testing has shown the following:
•
All color copiers/printers experience a higher jam rate when
performing duplex copying. Paper jams can be caused by the
curl created when running the side one image.
•
Increased jams from the Paper Tray Bypass result from the
contamination of feed rolls with fuser oil, when running a large
number of two sided copies. This contamination may require
more frequent cleaning of the rollers. To help reduce this
contamination problem, and improve feeding reliability, mix one-
sided copying jobs with two-sided copying jobs when possible.
During large two sided jobs, periodically run five blank sheets
from the Paper Tray Bypass in the Black Mode to help keep the
feed rolls clean.
•
Image quality on side two will usually be equal to the side one
image, but is more likely to have image mottle/light area
problems caused by slight waviness in the paper and variable
toner transfer. Both of these factors are greatly influenced by
paper quality.
•
To avoid intermittent side two deletions, consider running a
coated cover stock 60 lb / 160 g/m
•
Coated text papers 80 lb / 120 g/m
3 without second side deletions. However, when running 80 lb /
2
120 g/m coated paper from Trays 2 and 3, customers may
experience reduced gloss on side two, first sheets out may have
higher gloss, multisheet feeds, jams and possibly poor toner
adhesion. If you experience multisheet feeds, you will need to
run 10-25 blank sheets to clean off residual toner that may be
on the Fuser Roll.
Running any coated papers other than 80 lb / 120 g/m
Trays 2 and 3 may result in unacceptable performance.
