FJSOP2 - Daily Maintenance for AMS/APS Printheads
SCOPE:
All AMS/APS (Automatic Priming System) Printheads.
PURPOSE:
Detail the procedure for performing the required maintenance
routine for Foxjet AMS/APS High-Resolution inkjet printheads.
RESPONSIBILITY:
Customer.
SAFETY
:
All personnel performing this procedure must wear proper eye pro-
tection and latex gloves.
FREQUENCY:
This procedure is to be performed daily, or as often as required,
depending on print quality.
PROCEDURE:
1. Using a lint-free
cloth
, carefully clean any corrugated dust, hot melt glue strings and/or
other debris from the faceplate area. Be sure to wipe down the faceplate in one direc-
tion, NOT UP AND DOWN OR BACK AND FORTH, to lessen the likelihood of debris
being pushed into the center slot that protects the CP/OP (nozzles). Failure to wipe in
the appropriate direction may cause blockage in the CP/OP.
2. Press and release the Purge button to initiate an automatic prime/purge cycle (observe
that the ink is vacuumed off the CP/OP).
3. If necessary, wipe excess ink from the bottom of the faceplate with a lint-free cloth. If
ink continues to drip onto the faceplate when the Purge button is used, contact your
FoxJet Service Representative.
4. Verify that all screws are in place and that covers are clean and properly installed.
5. Insure that the front of the printhead is parallel to, and within 6mm (0.25") or less, of the
side of the carton as it passes in front of the printhead.
6. Insure that the conveyor guides are adjusted to prevent cartons from contacting the
printhead.
7. Run a print sample to ensure all the channels are printing and producing good print
quality.
IF PRINT QUALITY IS ACCEPTABLE, PROCEED NO FURTHER.
8. Press and hold the Purge button for five seconds to prime the system or purge air from
the printhead.
