Requests for Daily Care and Maintenance
This machine is a precision machine equipped with extremely fine mechanisms. Especially, the nozzle sur-
face of the heads from which the ink is discharged is affected even by a slightest attachment of dust or paper
powder and the proper printing results could not be obtained. With a view to using this machine in a better
condition, we would like to recommend performing the following care and maintenance on daily basis.

2. Daily care
(1) Surroundings of the heads ("Cleaning the Head and the Area around It" Chapter 4 of
the Operation Manual)
1Move the carriage to the left and open the
left maintenance cover.
• Refer to the Step 1 to 5 of Chapter 4 “Cleaning the
Head and the Area around It” of the user’s manual to
perform the operation.
2Clean the head and the surrounding area.
• Gelled ink and dust could stick under the slider and the surroundings of the head.
• Scrape them off with clean stick etc. In this case, never rub the nozzle portion of the head.
• When possible, use the cleaning stick (SPC-0527) for cleaning around the head/ capping station/ wiper.
Using the other cotton bud may attach lint, then it may damage the machine.
• Be sure to perform maintenance for the ink cap and the wiper of capping station every day. If you leave it
dirty, dirt may adhere to the nozzle surface, or, dust and dry ink may be rubbed against the nozzle. It may
cause discharge defect.
• Clean the bottom of carriage every day so that it will not get dirt from inks or dusts. If you leave it dirty, dust
and dry ink may be rubbed against the nozzle at wiping operation when performing head cleaning.
• When you clean the carriage bottom surface, fully be careful not to rub the nozzle surface.
• The heads and their surroundings are the parts most liable to be tainted in this machine and if
tainted, it could cause adverse effects to the functions of the machine and the results of the printings.
Moreover, as the head itself uses very fine mechanisms, sufficient precautions are required for the
care and maintenances.
