Cleaning; Exterior Cleaning - Printronix T8000 Administrator's Manual

8. During the last step of Manual Calibrate, the printer will advance the media and attempt to detect the
label length indicators and stop at the Top-of-Form position. The Sensed Distance value will then
display for one second. The calibrate is successful when the Sensed Distance value correctly matches
that of the installed media. If "CALIBRATION FAIL" error displays, run Manual Calibrate again.
NOTE:
The amount of media sampled during Manual Calibrate is based on the length of a label and
the transitions detected without error, between a label and its label length indicators.
9. Press the PAUSE key to place the printer OFFLINE (Home Screen).
10. Press the FEED key several times. Each time you press FEED, the media advances one label length
and stops.
NOTE:
After a form feed, the position of the leading edge of the next label depends on the type of
Media Handling mode selected via Media > Handling > Media Handling. Tear-Off and Tear-Off
Strip Media Handling positions the label edge at the tear bar, while Continuous positions the
label edge under the printhead.
11. Once the correct values are confirmed, save them to the desired configuration menu before powering
off the printer. See Saving a Configuration page 53.

Cleaning

Depending on the media used, the printer may accumulate residues (media dust, adhesives, etc.) as a
by-product of normal printing. To maintain top printing quality, you should remove these residues by
cleaning the printer periodically.
WARNING
Set the printer power switch to O (Off) prior to performing any cleaning tasks.
Leave the power cord connected to keep the printer grounded and to reduce the
risk of electrostatic damage.
IMPORTANT
When the printer is powered Off, menu settings that were changed and not
saved an any print data remaining in the print buffer will be lost. To prevent the
loss of recent menu changes, see Saving a Configuration page 53
CAUTION
• Do not wear rings or other metallic objects while cleaning any interior area of
the printer.
•
Use only the cleaning agents recommended in this section. Use of other
cleaners may damage the printer and void its warranty.
•
Do not spray or drip liquid cleaning solutions directly into the printer. Apply the
solution on a clean lint-free cloth and then apply the dampened cloth to the
printer.
•
Do not use canned air in the interior of the printer as it can blow dust and debris
onto sensors and other critical components.
•
Only use a vacuum cleaner with a nozzle and hose that are conductive and
grounded to drain off static build up.
•
All reference in these procedures for use of isopropyl alcohol requires that a
99% or greater isopropyl alcohol content be used to reduce the risk of moisture
corrosion to the printhead.

Exterior Cleaning

Clean the exterior surfaces with a clean, lint-free cloth. If necessary, use a mild detergent or desktop
cleaning solution.
