4.2 Error Process
4- 2
4.2 Error Process
When the printer detects the errors shown below, it sends the error state to the PC by the ERROR LED and
DATA LED, and stops the operation, waiting for a command from the PC or a restart.
The printer will restart the operation after clearing a feed jam, media end, cover open, or print head overheat error
which occurs during printing, or after supplying the media when the printer has run out. For all other errors,
however, the printer does not restart the operation after clearing the error, it is necessary to resend the command.
Regarding the print head broken element error, the printer stops every operation except a status response.
1. Command error
(1) This error occurs if an error in the command length, the command transmission sequence, the command
format, or the parameter designation is found during the command analysis.
(2) This error occurs if the form No. designated by the data print command has not been registered.
2. Feed Jam (Paper Feed Error)
(1) This error occurs if the printer fails to detect the gap between labels even after feeding the label for 1.5
times as long as the label pitch designated by the label size setting command. (Only when the feed gap
sensor/black mark sensor is designated.)
(2) This error occurs if the printer fails to detect the black mark for the auto feed function even after
feeding the media for 180 mm when supplying the media, turning the Stand-by switch ON, or closing
the cover.
3. Media End
This error occurs if the printer detects the label end for 20 mm during label issue or feed. However, if more
than 90% of effective print length has been printed and no more print data remains, the printing terminates
normally. Also, if a media end is detected in the middle of printing and unprinted data remains, the printer is
in the state waiting for issue (wait for media supply).
NOTE: Detecting a media end state during media feed results in no error.
4. Cover Open error
(1) This error occurs if a cover open state is detected while the printer is printing or issuing the media for 5
mm.
(2) This error occurs if a media issue or feed is attempted while the media cover is opened.
5. Print Head Broken Element error
(1) This error occurs if a broken element is detected during the automatic missing dot check which is
performed when the Stand-by switch is turned on or the cover is closed.
(2) This error occurs if an error occurs in the print head driver.
6. Print Head Overheat
This error occurs if the thermistor of the print head detects abnormally high temperature.
7. Flash ROM Data Write Error
This error occurs if an error occurs when data is written into the flash ROM.
8. Flash ROM Data Erasing Error
This error occurs if an error occurs when the flash ROM is initialized (data erasing).
9. Wait for issue (Wait for media supply)
(1) This error occurs if a print command is received when the media has run out.
(2) This error occurs if more than 90% of effective print length has been printed and unprinted data remains
in the media end state. For example, when issuing some cut forms, the media needs to be supplied one
by one. Then, the printer’s wait for issue state is sent to the PC each time a cut form is issued. Printing
terminates normally when the last label is issued, as no more data remains.
10. Area Full in the Flash ROM
(1) This error occurs when the form entry area in the flash ROM becomes full.
(2) This error occurs when the data of 4KB or more is sent when the form entry is performed while the
form No. “00” is designated.
NOTE: When an undefined instruction execution error occurs, the printer will be automatically reset.
