Staple Feasible Paper Weight
2
When stapling is specified and the paper weight exceeds 34 lb. (128 g/m ) the
printer will deliver the job offset with no stapling.
Staple/Offset
When stapling and offset are both specified, the job is delivered stapled with no
offset.
Collate
For collated output disable the application software and enable the printer driver.
Report/Test Print
When report and test printing are chosen from the OCP while a job is printing, the
report and test are printed after the current job is complete.
Printing is Offset in Booklet
Depending on paper thickness, slippage may occur during the folding process.
For this reason, print should be a minimum 10mm away from the fold.
Perform a test print to check print quality prior to starting daily print jobs and
prior to starting jobs requiring high print quality.
Continuous half-tone or solid black printing may cause print quality degradation.
Frequent high black-to-white ratio and high-density printing can cause degraded
print quality such as black dots or offset. Check the print quality periodically and
clean the inside of the printer as described in "Cleaning the Printer" on page 6-41.
Color printing causes more toner scatter than black printing, which results in the
inside of the printer becoming dirty easily. Check the print quality periodically
and clean the inside of the printer as described in "Cleaning the Printer" on
page 6-41.
A high black-to-white ratio on duplex print jobs can cause paper to stick to the
finisher. To avoid this problem, remove paper from the finisher stack frequently
or lower the print density.
Print density may be high for several thousand pages after powering on the
printer. If that is the case, set the print density to "Light" for several thousand
pages, then return the print density to "Medium". See "Print Density Adjustment"
on page 6-57.
Print density may be gradually decreased by continuous low-density printing.
Print several hundred pages of a half-tone pattern to increase print density.
After continuous printing of thick paper, the first sheet of a new print job may
pick up dirt from the fuser unit. Run a cross-pattern test print to remove dirt.
