Maintenance Overview 174
6.1.3 Service Maintenance
If print irregularity (missing dot, white line, etc.) has occurred or the printer
indicates "Maintenance Error", take the following actions to clear the error.
6.1.3.1 Head Cleaning
The printer has a built-in head cleaning function, which is activated by
operating the control panel.The procedure is given below.
1. Confirm that the printer is in stand-by state.
Check that the Power LED is not flashing.
2. Hold down the Ink Switch on the control panel for more than 3 seconds.
The Power LED flashes during the cleaning sequence.
6.1.3.2 Maintenance Request
Ink is used for printing and Head Cleaning. Waste ink is drained into the Waste
Ink Pads via the Cap Unit, and its amount is stored into the EEPROM's
Protection Counters (Waste Ink Counter) A and B (located near the home
position or the opposite side). When the preset value is reached, the Waste Ink
Counters detect that the Waste Ink Pads have reached the absorption limit.
The printer displays "Maintenance Request" to request the Waste Ink Pads to
be replaced.
Protection Counter A+B Limit
Up to 17772
Timing for Replacing the Waste Ink Pads
When the Protection Counter reaches the value shown above, a
Maintenance Request is indicated, and the printer disables all switches
except the Power switch.
Since the Protection Counter value can be confirmed in the adjustment
program, be sure to check the value when servicing regardless of
whether the service is related to the Waste Ink Pad or not. If the
Protection Counter value of that printer is close to its limit, inform the
user about that, and replace the Waste Ink Pads and reset the
Counters with the user’s permission. (If the Waste Ink Pads are not
replaced at that time, it is expected that the printer will be returned for
repair in the near future due to a Maintenance Request error.)
Under the specific conditions, the limit level of the counter is preset to
25000 pages for black ink or to 10000 pages for color ink. We assume
that the limit level will be reached in about 3 years in normal use.
Replacement Procedure
Replacement of Waste Ink Pads in Disassembly and Assembly
(Refer to 4.2.2 "Waste Ink Pad" on page 80.)
After the Replacement
Reset the Protection Counter (Refer to Chapter 5 "ADJUSTMENT")

For Head Cleaning, it is recommended to run the nozzle
check and the cleaning alternately to minimize ink
consumption.
