Cautions On Operating Time When Printer Is In Service - Hitachi IJ UX Instruction Manual

1.5 Cautions on operating time when printer is in service

(1) Cautions when printer is repeatedly stopped immediately after the start
of operation
If you repeatedly stop the printer immediately after the start of operation, automatic nozzle cleaning at shutdown
will cause the ink in the IJ printer to gradually become thinner. For stable operation of the IJ printer, operate the
printer for a given amount of time or more once started.( =in Ink eject status)
During the operation, the ink viscosity is adjusted automatically and returns to the initial value.
The required amount of operation time varies depending on the ambient temperature or ink types used.
Refer to the handling guidance of each ink for details.
(2) Caution when daily operating time is relatively long
The IJ printer emits an ink jet when printing, so the outside and inside of the print head cover will become dirty
with accumulated ink spillage during operation. To prevent printing defects due to this ink accumulation,
periodically check the head cover and clean it as required.
1.6 Heating of ink
(1) If the ambient temperature is under approximately 20 C, the ink is heated by a heating unit in the print head.
The startup processing time relative to when not operating becomes long.
When not operating: Approximately 1.5 minutes
When operating: Maximum approximately 10 minutes (The rise processing time changes depending on the
(2) When a heating unit fault occurs, take care of the following items.
1 If a heating unit fault occurs, the messages "Ink Heating Unit too High", "Ink Heating Unit Temperature
Sensor Fault", or "Ink Heating Unit Over Current" are displayed and the IJ printer fault stops.
The IJ printer can be restarted by pressing the Reset or Close . However, the ink will not be heated even
if the temperature drops thereafter.
2 Once "do not perform ink heating" is set, the following message is always displayed whenever the power
is turned on thereafter. Cancel the message by pressing the Close and be sure to inform your nearest
local distributor.
Ink Temperature Correction Notice
The selected setup does not allow ink temperature corrections
to be made.
Solution Contact your local distributor.

3 If the printer is temporally operated in "do not perform ink heating" status, the operation of the printer
may become possible by resetting the excitation voltage.
Reset the excitation voltage according to Technical Manual "6.10 Excitation V Adjustment".
