=msg 601 on LR3300 / LR5200 with polygon mirror
LR ‘’high res’’ measures the laser brightness with the BOL (begin of line) sensor. in case, the polygon
mirror does not turn, you also get error 601! This has nothing to do with calibration!
How to check, whether the polygon motor turns.
Remove black cap over green LED on polygon control board wiht some tweezers. Green LED must
be on.
Reason: Polygon motor does not turn: Polygon or polygon control board defective. Cable not
connected. 24 V missing.
Cure: Check cables. Exchange polygon or exchange polygon control board. Exchange 24V
power supply.
Reason: Shutter doesn’ t open. Shutter or laser calibration board defective. Cable to shutter not
connected.
Cure: Check cabling to shutter, Replace laser calibration board or shutter.
=msg 604
Meaning: Image FIFO of FOI board timeout: For 5 minutes no image data were transmitted,
despite print order was sent by controller.
This is an internal error only. The laser imager gets the print command for this film
once more.
(This error is displayed in the error ringbuffer and the logbook only)
Reason: Problems with FOI Board on MG3000 output (should be rev. E..F).
Cure: Check AMDI protocol on both sides: At laser imager and at Controller. Check whether
there are intermittent transmission problems. Check cable connection.
Replace FOI board (at Controller) if necessary.
Reason: Due to SW problems in the Controller the image data could not be sent in time.
Upgrade Controller SW (to MeGa3P31 or higher)
=msg 605
Meaning: Laser imager transmits three consecutive "lock errors" to the controller.
Reason: The oscillating frequency of the galvo is wrong or disturbed.
Cure: Replace galvo (replace it always together with 310 GS galvo control board)
Cure: Check the + 15V DC on 132GS scan timing board and 310GS galvo control board
Cure: Check the + 18V on 130GS (power supply print engine), 134GS (I/O bus laser control
board) and 132GS (scan timing board).
Cure: Vibration for the period of transmission of data.
Temporary fault or permanent fault due to floor vibrations.
=msg 606
Meaning: "FOI violation error".
This is an internal error only. The laser imager gets the print command for this film
once more.
(This error is displayed in the error ringbuffer and the logbook only)
Reason: Interrupt during image data transmission.
Cure: Check FOI cable. Short circuit it at one end and look at AMDI protocol.
=msg 607
Meaning: "Start of image too soon"
This is an internal error only. The laser imager gets the print command for this film
once more.
(This error is displayed in the error ringbuffer and the logbook only)
Reason: Controller sent already image data, but laser imager was not ready.
Problem with synchronization. Image transmission before start of image request.
Cure: Check revisions of laser imager and controller FOI boards:
Laser Imager: rev. D and higher.
Controller: rev. E and higher.
Check FOI boards. Short circuit it at one end and look at AMDI protocol.
The commands <DC2> and <DC4> should be visible.
Replace FOI board.
=msg 608
Meaning : "FIFO (of FOI board at laser imager) full at end of image" (=EFI
error)
This is an internal error only. The laser imager gets the print
command for this film once more.
(This error is displayed in the error ringbuffer and the logbook only)
Reason : Imager exposed the right number of pixels, but there are still some
pixels left in the FIFO of the FOI board "data underrun". (either too
many data were sent or too less data were read).
Cure : Check FOI cable. Short circuit it at one end and look at AMDI
protocol.
Check FOI boards. The commands <DC2> and <DC4> should be
visible with AMDI protocol.
Reason : Problems at switching from "border value" to "image info" in case the
text feature in the border (terminal: lctrl>manufacturer) is switched
on. Only possible as of LTP1405. (How to recognize: There is a
small white textline on the top left border diplaying filmtype and so
on)
Cure : Switch off the textline. Press <ENTER> at display "TERMINAL:
>lctrl>manufacturer, so that no manufacturer is entered, and so this
feature is switched off.
Reason: : in combination with a „ghost image“ (= image seems to be repeated
2 cm on the right): Disturbed BOL (begin of line) signal.
Cure: : Upgrade device SW to LTP1805 or higher.
=msg 609
Meaning: „EFI_D_UR_ERROR“ = Image data FIFO empty during transmission (data underrun).
Reason: FOI transfer speed too low. FOI at LR High Res and MG3000 lower than rev. F (must
be ³ F at both sides!) MG3000 FOIXXX11 parameter transfer_mode not on 1 (must be
1). AMDI motherboard not rev. 3 (at least). Monitor version on MG3000 not 4.22 or
higher.
Cure: Exchange FOI board at LR High Res and at MG3000 to rev. F or higher. Install
MON4.22 or higher on MG3000. Change FOI parameter transfer_mode to 1. Check
AMDI motherboard: Must be rev. 3 or higher.
Reason: : in combination with a „ghost image“ (= image seems to be
repeated about 2 cm on the right): Disturbed BOL (begin of line)
signal.
Cure: : Upgrade device SW to LTP1805 or higher.

Cure: Reset the printer. Check IO Bus cable connection between RK188 and Laser Control
board 134GS. Eventually change 134GS (IOB Laser control-HR board)
=msg 621
Meaning: Polygon rotates with incorrect speed (most likely it is 0)
Reason: Start signal on pin 4 (plug J4; polygon motor controller 310GS) not present.
Cure: Check voltage between pin 4 and 7 at J4 on 310 GS.
0V Æ problem of 310GS or polygon (hall feedback sensors!)
+5V Æ problem of laser control board 134GS or cable between laser control board
and polygon motor controller.
Remark:+5V on pin 4 is the signal generated on laser control board to switch off the
polygon motor! To switch the motor on , the signal is changed to 0V.
Reason: Missing 24V of power supply 106GS
Cure: Check presence of 24V at plug J2, polygon motor controller 310GS.
