With more use, you will have less troubles. Keep the printer in good condition.
|
As you may know, the inside of the inkjet printer is not very clean. Wet ink mist may collect dust and thread around maintenance units and may damage the print quality. So routinely check the inside sometimes before turning ON and keep your GT-782 in good condition.
|
Before you start:
|
Select the menu in [ Maintenance ] e.g. [ Cap/Wiper Clean ] and [ Nozzle Cleaning ] and the maintenance devices will move to a better position for cleaning. Then turn OFF the printer and open the front cover.
|
|
The check points are the same as GT-541; wiper cleaners, print head caps, wipers, flush plates, the front/back of obstruction sensors, Platen sheets and T-shirt tray.
Click the position and you can jump to it.

Wiper Cleaner and Wiper Cleaner Cassette
The most important point is to keep the wiper cleaner clean "enough to absorb ink", which holds waste ink inside of it to keep the surface of the wiper blade clean, so that print heads can fire properly.
In other words, maybe head cleaning may not solve the misfiring and banding. Remember, wiper cleaner cleans the wiper blade, and the wiper blade cleans the print heads. If wiper blade is muddy with waste ink because wiper cleaner is muddy, then how can print heads
keep clean? So check the wiper cleaners every time the warning is indicated on the control panel. Use plastic gloves in cap cleaning kit if it is too dirty.
Refer to "Maintenance" page in basic operation manual or instruction manual for "step by step" instructions.

If you have not exchanged the wiper cleaner for a long time, please be careful, because waste ink may overflow inside wiper cleaner cassette. Pull it out slowly and carefully not to spill everywhere around the printer.
|
Be sure to place the wiper cleaner properly into the wiper cleaner cartridge (black body) and put it back into the printer. When the claws are off or wiper cleaner is not inserted to the back position, it will hinder the wiper and another misfiring might occur.
|
Caps / Wipers
When you exchange wiper cleaner, check the caps and wiper blade as well, with the cap cleaning kit if they are dirty with ink or dust. Read the manual before cleaning.

Flush Plate
When ink or dust is mounted high on the top edge of the flush plate, it may touch the surface of the print head during printing, this may cause misfiring. Wipe off the dirt with a soft wet cloth with water.
|
|
Front / Back of Obstruction Sensors
Check the front/back surface of the obstruction sensor not to damage the printing material when loading. If they are dirty with ink and/or dust, wipe off the dirt with a soft wet cloth with water.

|
Platen sheet
This cotton sheet is for holding a printed material flat. In addition, it catches the small mists of ink coming through the material as well. When the edges are loose and the surface wears out, peel it off and put a new one. If you feel is hard to peel off, warm
the surface with hair dryer to loose the adhesive tape.
|
|
T-shirt tray
There must be much dust mounted at the back corners. Wipe off the whole surface sometimes.
|
|
After closing the Front Cover:
|
At the end, check the inside of waste ink tanks, especially the one for white, or your floor might suffer from waste ink flood...
