Print Quality
Use the following Print Quality options to improve the appearance of print jobs.
●
Color Calibration
◦
Power On Calibration. Specify whether the printer should calibrate when you turn it on.
◦
Calibration Timing. Specify how frequently the printer should calibrate. The default setting
is 48 hours.
◦
Calibrate Now. Click to calibrate the printer immediately.
●
Optimize
See the following table for the options available under the Optimize menu.
NOTE: HP recommends that you change the Optimize settings only if an HP customer support
person advises you to.
Table 1-3 Optimize Modes — Optimize menu
Adjustment Range (*default) Description
Background toner Off*/On Optimize printer settings to reduce
background toner. (Glossy media picks
up background toner more readily than
plain media.)
Extra drum cleaning Off*/On Talc from paper with high talc content
gets coated on the imaging drums and
degrades the image quality. The printer
will use extra cleaning rotations when
stopping to eliminate this coating on the
drums.
Drum banding Off*/On This mode reduces the occurrence of
sharp lines at the OPC drum pitch
(75mm) by extra pre-rotations and by
jogging the drums slightly after each job.
The jogging motion is slightly audible.
Transfer belt cleaning Off*/+1 to +2 This mode increases transfer belt (ITB)
cleaning effectiveness by increasing the
ICL (ITB Cleaning) roller/brush voltage
for the +1 setting, and by increasing
cleaning frequency for the +2 setting.
This should be used when the ghost of
previous heavy coverage pages appears
on following pages.
Transfer belt cleaning voltage Off*/–5 to +5 This adjustment allows fine control of the
ICL roller/brush voltage. Decreasing the
voltage is better for OPC drum ghosting.
Increasing the voltage is better for heavy
coverage cleaning.
Transfer belt voltage – Y Off*/–5 to +5 This adjustment allows fine control of the
Yellow station OPC-to-ITB transfer
voltage. (There is currently no known
defect associated with this adjustment.)
Transfer belt voltage – M Off*/–5 to +5 This adjustment allows fine control of the
Magenta station OPC-to-ITB transfer
