Alex Merola 0 Report post Posted September 5, 2013 hi, yesterday I had a similar problem had in the past on the 350, error w-2401, the paper does not advance in section 4-5, I went to setup and mantenimance, printer adjustament / mantenimance, printer i / o check, I tried to move (drive / stop) M541, repeatedly worked well but sometimes turning in the opposite direction!! on the 350 I had the similar problem but the M541 did not work completely, I had to change a drive on pdc20. Today the machine worked properly. What do you think? does anyone know if M541 can turn in the opposite direction and who controls it? THANK YOU Quote Share this post Link to post Share on other sites
ghn5ue 4 Report post Posted September 5, 2013 I haven't experienced this on a Fuji machine, but it's common for a stepper motor to turns backwards if the IC that drives it is faulty. The normal way to solve the issue is to replace the board, but somebody who is competent with electronics can replace the driver IC on the board. 1 Alex Merola reacted to this Quote Share this post Link to post Share on other sites
Minilab service 249 Report post Posted September 6, 2013 Probably Kokusan motor will be broken. Motor rotation direction depends on signal from minilab ( clockwise or counterclockwise ) . It is possible to repair this motor. Many times had to repair Kokusan drive motors - especially on Konica minilabs. 1 Alex Merola reacted to this Quote Share this post Link to post Share on other sites
focusonimage 1 Report post Posted September 9, 2013 You need to confirm if the D541 is working (via I/O check) that alarm occur when sensor does not detect paper's leading end within a specific time after the paper has been fed from first feeding section. If the motor is working in both direction without control, you need to change the PDC20 board. 1 Alex Merola reacted to this Quote Share this post Link to post Share on other sites
Alex Merola 0 Report post Posted September 12, 2013 for 5 days the frontier worked perfectly, yesterday crashed and took over the defect that the M541 engine has started to turn on the contrary, I restarted the frontier and it worked well, today is a tragedy hangs constantly. but if it was the fault of the board should not always PDC20 not work? sorry for the English is not perfect. Now I try to disconnect and reconnect the pdc20 knows it's just a bad contact Quote Share this post Link to post Share on other sites
Minilab service 249 Report post Posted September 12, 2013 I don't think will be bad contact. Guess it will be motor or motor driver intermittent fault. Quote Share this post Link to post Share on other sites

Alex Merola 0 Report post Posted September 12, 2013 https://www.dropbox.com/s/eywqqbztxlf8z0u/scheda%20pdc20.jpg I bought STK672-040-E - DRIVER, which will replace it as soon as it arrives, as I read that manual is the driver U44 on the pdc20 board but unfortunately there is silicone that hides me the number of the driver. Does anyone know what is the right position?I include photos on the link to dropbox Thank's a lot Quote Share this post Link to post Share on other sites
ghn5ue 4 Report post Posted September 14, 2013 It think that a diode in the stepper driver IC becomes leaky and will allow current to flow in either direction. That is why the motor will sometimes turn backwards. On older American made machines the diodes (regulators) were external (not in the IC) and you could test them and find the faulty ones. We had problems with them constantly on our old Hope minilabs. Quote Share this post Link to post Share on other sites
