Chapter 77-18Maximum value of "GAP gain": 255Maximum value of "GAP current value": 320When the multi sensor and media are normal, "GAP gain" is about 30-250; "GAP current value" is about 200.[Check 2]Check whether the multi sensor performance has degraded or whether the media is compatible.When "Density gain" and "Density current value" are maximum values and "Density media output" is 168 or less, an error occurs.Maximum value of "Density gain": 255Maximum value of "Density current value": 245When the multi sensor performance and media are normal, "Density gain" is about 5-100; "Density current value" is about 200.10) NOZZLE CHECKChecks for non-discharging nozzle with head management sensor.11) NOZZLE INFDisplays the result of non-discharging nozzle check performed with "NOZZLE CHECK" by nozzle row of each ink color.- Press the key or key to switch the ink color.- AE:A-EVEN row, AO:A-ODD row, BE:B-EVEN row, BO:B-ODD rowF-7-1412) MEMORY CHKT-7-2113) HEAD CNT CHKConfirms the contact status of the printhead.e) REPLACE1) CUTTERThis mode is for replacing the cutter.f) COUNTERDisplays the life (operation frequency and time) of each unit, print counts for each media type, and else.The count values can be printed from [PRINT INF].1) PRINTER: Counters related to product lifeT-7-222) CARRIAGE: Counters related to carriage unitT-7-23Display DescriptionDDR Checks the DDR-SDRAM mounted on the Main Controller PCB.EEP Checks the EEPROM.Display Description UnitLIFE TTL Cumulative number of printed media (equivalent of A4) sheetsLIFE ROLL Cumulative number of printed roll media (equivalent of A4) sheetsLIFE CUTSHEET Cumulative number of printed cut sheets (equivalent to A4) sheetsLIFE A-F Cumulative number of printed media for environments A to F sheetsPOWER ON Cumulative power-on time (excluding the sleep time) HoursW-INK Remaining capacity of the maintenance cartridge %CUTTER Number of cutting operations (count as 1 by moving back andforth)TimesWIPE Number of wiping operations TimesSLEEP ON Cumulative sleep-on time HoursDisplay Description UnitPRINT Cumulative printing time HoursDRIVE Cumulative carriage moving time HoursCR COUNT Cumulative carriage scan count (count as 1 by moving back and forth) TimesCR DIST.
