HP Latex 360 Printer - Manual (Page 154)

7. Slightly dampen the used cloth with 95% ethanol to wipe the remaining dry ink deposits from the
platen.
NOTE: Dry ink deposits take longer to remove.
NOTE: 95% ethanol is not provided in the User Maintenance Kit.
CAUTION: Ethanol is highly flammable. Observe the manufacturer’s safety precautions.
CAUTION: Do not use commercial cleaners or abrasive cleaners. Do not wet the platen directly,
because you will leave too much moisture behind, which could damage the substrate advance sensor.
8. Use the damp cloth to remove remaining dry ink deposits from the cutter ramp (360 only).
9. Close the 95% ethanol container and remove it and the cloth from the vicinity of the printer.
10. Wait 3 or 4 minutes to let the ethanol evaporate, before turning on the printer and reloading the
substrate.
11. With a 1 mm diameter pin ensure that the vacuum holes are not obstructed, especially the holes that
are covered by the most-used substrate sizes.
Clean the substrate-advance sensor window (360 only)
The substrate-advance sensor is the very small rectangular window (less than 1 square centimeter in size)
close to the third pinchwheel from the right.
HP recommends that you clean the substrate-advance sensor window whenever you clean the print platen
and if you are experiencing print quality issues.
1. Unload the substrate by using the front panel procedure. See Unload a roll from the printer on page 66 .
2. Turn off the printer and wait until it has cooled down.
