Cleaning the Printer
Clean the printer a few times a year to keep the printer operating properly.
While cleaning, be careful not touch or soil any of the gears and the carriage
encoder strip behind the carriage movement space.
Never use alcohol or thinner to clean the printer. These chemicals can damage the
printer components.
Do not use a hard or abrasive brush.
Do not lubricate the inside of the printer. Unsuitable oil or lubricants can damage
the mechanisms.
1.
Turn off the print engine power with the POWER key on the control panel. When
the print engine power down sequence is completed, turn off the main power
switch in the rear of the printer.
2.
Open the printer cover.
3.
Using a soft brush, clean away any dust and dirt inside the printer.
4.
Clean the maintenance station, wiper blade and around the nozzle plate.
5.
Empty the waste ink bottle.
6.
Replace or wash the ink drip foam as well as the two lower waste ink foams.
7.
Close the printer top cover.
8.
If the outer cover is dirty, clean it with a soft damp cloth with mild detergent. Make
sure the water does not seep into the printer’s mechanisms.
9.
Using a damp cloth, clean the print table with mild detergent.
Maintenance/White Ink
Due to higher concentration of solids and heavier white ink pigments, white ink can
clog the ink delivery system and print heads. When white ink cartridges are installed in the
printer, more frequent head cleaning and regular maintenance operations are necessary.
The garments should never touch the print head or nozzle plate as it can scratch the nozzle
plate coating or cause clogging of the nozzles. This is particularly true when printing with
black garments sprayed with pretreatment liquid. Adjust the print table height so that the
garments will not touch the print head nozzle plate.
The periodic printer maintenance takes an added importance when the printer is used
for black garment printing. The white ink contains a higher percentage of solids than
colored inks, resulting in more ink residues accumulating on and around the print head,
wiper blade and maintenance station. When white ink is used, the white residues
accumulating around the maintenance station and nozzle plate cause the maintenance
station not to seal properly during cleaning cycles. The pretreatment applied to the
garments also leaves residues on the print head area. All these accumulation of foreign
materials will tend to clog the print head and shorten its life unless the residues are
removed regularly.
