  1. we need more information what is the direction of paper travel? I suspect the line is across the width? if so the paper is stop starting so cleaning the belt was the first step. Its a repeated consistent banding line so it could be the subscan roller bearings, remove the belt with a gloved hand and spin the rollers listen for rough bearings or sticky points it doesn't take a lot to band. If the lines are down the print travel look at the racks on entry to P1 and P2 for any build up that can bruise the emulsion causing Plus density lines, hard to see from the one sample
  2. Sorry its not the laser glass or focal guide its classic banding your paper is stop starting, juddering, stop gives a plus density then light line. as above check your belt and bearings look for any black powder from the bearings a sign they are failing, check the belts for deposits and on the pullies. it doesn't take a lot to cause banding looking again also check the paper is going into the reverse unit correctly and the reverse unit upper roller is held open to accept the leading edge. The banding looks to be in a consistent place xx mm back from the leading edge. The upper roller is held open to receive prints by a small bearing on a black arm that rides on a cam at the back of the reverse unit. Often the black arm is broken or distorted or the plastic holding the top part breaks off the shaft its moulded on to
  3. E-4748 The AE retry-over occurred. Restart the system. If problems persist, consult your technical representative. At the time of AF, scanner correction, brightness correction, or AE (Causes of the error message) 1. Faulty harness between CCD23 and GIA23 circuit boards 2. LED light amount too large 3. Faulty CCD 1. Reconnect or replace the harness. 2. Perform Menu 0349 “LED Light Amount Adjustment”. 3. Replace the CCD unit. I suggest you reseat all cables and PCBs as a first step
  4. From the manual E-4764 The external memory of GIA circuit board is abnormal. Restart the system. If problems persist, consult your technical representative . Result of GIA23 circuit board external memory R/W was NG. (Causes of the error message) 1. Poorly inserted GIA23 circuit board into slot of GMB23 circuit board 2. Faulty GIA23 circuit board 1. Insert the circuit board into the slot correctly. 2. Replace the circuit board.
  5. You are trying to colour match quite different machines, is your 38 HD? Daily set up is different as is black balance etc. Check to see If you have any hidden corrections in either individual channels or paper setups you may have to visually determine the difference between the 2 and input the correction into paper balance to get them closer. from the samples 1 is lighter than the other anyway. when you have worked out the correction put it in all papers. Daily set up will bring it back to the same starting point each day. The 38 has a machine matching function but not the 31, better to get it as close as you can visually without going down the profiling route
  6. I'm guessing this is on glossy paper. I have had similar events on several Noritsu machines caused by the tail end of the paper sticking to the guides at the cutter end. The arm moves across with the leading edge and just before it gets to the exposure advance the paper sticks and the arm drops the leading edge. Worth a look with the door open, I have had several faults on longer prints on 37 type machines and lifting the guide with a washer is enough to stop the glossy paper sticking to the chrome plates in that area, maybe its static and a few strips of Teflon tape may help
  7. Look in AFC adjustment with the service password. look for any sensor LED light intensity at 255. These are maxed out and need to be replaced. The LEDs are on all the time the neg mask is in position and the light output gets weak with time so the machine ramps up the LED to compensate. when it gets to 255 it cannot go any further. The LED is easy to replace though you have to dismantle the mask from its rails as the LEDs are all in the bottom. Normally you don't adjust or touch the photo transistor in the hinged part (top) the DX ones are not easy to replace and I would leave those alone. Each LED is mounted on a small PCB 25mm x10mm or so. The LEDs can be replaced with standard crystal clear green LEDs I bought some from ebay. Mine were brighter and a bit of a colder green, The ones fitted are a yellow green. They worked fine but as they are brighter the mask once calibrated was down to 65 instead of the normal 80. As long as they can detect film no problem. Take care with the orientation of the LED, the PCB is marked +-
  8. This is a simple fault on box chemistry. It knows how many prints can be processed before it SHOULD run out of replenished. Yours has not run out so it will let you carry on for a while then give the error. Go into Maintenance mode Processor and input check This will show your tank levels for P1 P2-A and P2-B, I suspect 1 or more are empty with the other still showing half full. That's the one that you need to look at to ask why? The box should have all the chemicals running out at the same time. You need to check your replenisher pump outputs are correct, maybe needs new poppet valves or a pipe is blocked kinked etc. Once you think you have a reason for it not to be empty simply drain all the rep tanks, The taps are normally below the position of the replenisher box. Not the same taps for draining the main tanks. Once drained it should ask for water to be filled and a new box and the door shut. It should then do a mix as normal. If it doesn't you can make it do a mix from normally the installation screen, more info on the model would help, I'm presuming Fuji
  9. On the other side especially with the demise of lab outlets in the UK with both Asda and Boots pulling out of wet lab and film processing in particular I see a gap for those left processing film. Your arty farty film is best brigade still want to shoot film. Processing the film needs to be done correctly at a Premium price but its no good if your film processor process is poor or scratching due to lack of use. think about offering a bit more than the disposable market wants maybe a dev and digital contact sheet process, most digital labs can scan and print a contact sheet. with upwards of 400 less outlets in the market its worth a shot, start with process control, half the problems you get are due to low utilization so think about only running the machine 2 or 3 times a week rather ran it churning away day in day out turning your Dev into Guinness
  10. Very few did when it was common practice to read one before processing. I had a guy who kept 3 good ones in his draw and read those each day gaining a Kodak award for consistent process control. The fact the image on the neg was so light the neg mask wouldn't print anything didn't seem to attract his attention
  11. If you are looking for the maintenance mode that does give you options an operator would normally see the password is 2260 From the menu that shows extension, before going any further press F1 AND F9 at the same time it will ask for the password then go to the mode you want you will have extra function not seen till then. DONT mess with things you don't know or you can mess it up. If not this please try to tell us what you are trying to do
  12. Pull out the top magazine tray on the left hand side you will see half of the sensor fitted to the side of the tray. it has a small 8mm wide stainless steel cover protecting the rear side of the sensor PCB. Check that it is not touching the rear side of the sensor. They have a knack of getting bent in and will short out the voltage going to it and others on the same supply. Worth a check
  13. 1st thing to check with any machine is chemistry. Time temperature and concentration, Time is taken care of by the rack, has it reached temperature? Check the recirculation filters are not clogged. Is it fresh chemistry or been sitting in the machine unused and unloved for some time. In the Old days you processed a control strip and read it with a densitometer comparing the readings with a master supplied. You could spot problems with recirculation replenisher rates before it showed in your work. A black art these days. Most don't know how or do this so simply process some paper 1st fogging the leading edge. Leave 1 inch sticking out the magazine when you load the magazine, Noritsu's will normally ask do you want to feed lead paper, YES. The unfogged paper should be white, the fogged paper black. If its not your chemistry is no good and needs replacing. The test paper has not been exposed by the machine so its should be black. If it is black and only looking blue on images exposed by the machine then its a set up issue
  14. You show the keyboard ribbon cables removed. These use a graphite type contact strip that often don't make a good contact with the receptor. Clean the very end of the transparent strip and contacts with a pencil eraser {not to hard or you will rub away the conductive surface} refit and try again, you can test each button for a beep but they often work in that way but not when pressing say yes and no at the same time. if no good I would go keyboard first
  15. Undo the bolts holding the motor undo the grub screws on the pulley turn the bolts round from the motor and screw them into the other blind holes, they will push the motor back off the pulley or at least with the bearings, clean any burrs of the motor shaft with a file to help getting if off next time
