5.5.19 System Error 1800: PTG Register R/W Error
<Description>
Could not read or write normally the PTG register.
This error is detected through the process below:
(1) The printer is started;
(2) The printer writes test data on the PTG register in 16-bit access; and
(3) Though the printer reads the data on the PTG register, the read data is not same as the
written data.
<Faulty part>
(1) Carriage cable (FFC): CARRIAGE FFC, MW
(2) PCB-ASSY-HCB1M
(3) PCB-ASSY-IPB5-100
(4) Robot cable: ROBOT CABLE, MW
<Action>
Restart the printer.
If the error persists, check the
Items to be Checked
on the table below, and perform the actions
starting from the top until the problem is solved.
Note:
For this error occurs, be sure to perform the following items 1 to 4.
No
Items to be Checked
Action
1
The width of the V-shaped folded
part on the PCB-ASSY-HCB1M-side
FFC
Check that the width of the V-shaped folded part on the
FFC is proper. If not, adjust it. For the adjustment
procedure, see
6.8.4 PCB-ASSY-HCB1M
.
2
FFC’s external damage
Check the following to ensure that the FFC is not
damaged.
-
FFC’s terminal is detached from its base.
-
FFC’s edges have not been abraded by friction.
If the FFC is damaged, replace it.
3
FFC
’s connector connection
Reconnect the FFC on both the PCB-ASSY-HCB1M side
and the PCB-ASSY-IPB5-100 side.
If the cable terminals are smeared, softly wipe them with a
soft cloth or lint-free paper dampened with ethanol before
connecting them.
4
Robot cable’s connector connection
Reconnect the robot cable on both the
PCB-ASSY-HCB1M side and PCB-ASSY-ACT3 side.
Before connecting, check that the connector terminals and
cable connection part are not disconnected. If a
connection failure is found, replace the robot cable
5
PCB-ASSY-HCB1M
Replace the PCB-ASSY-HCB1M.
6
PCB-ASSY-IPB5-100
Replace the PCB-ASSY-IPB5-100.
7
FFC
Replace all four FFCs.
8
Robot cable
Replace the robot cable.
