This is a SNIP of a rather LONG FIX: Found here: http://forums.windrivers.com/showthread.php?7080-RESOLVED-Okidata-Microline-184-Turbo "Just purchased this thing and am running it a machine to print checks with (Win95, p1-200, 48 Mb ram). The Oki dot matrix printers don't give you drivers, they tell you to use the drivers from Win95 disk. Sure... (just lazy if you ask me :-) OK using the Oki Microline 184 IBM Turbo driver the thing works fine, EXCEPT that it *always* prints in NLQ mode no matter what the settings in the control panel, it just switches to NLQ before each print job. So... we switch to a "generic text" driver and it works fine that way EXCEPT that it no longer recognises the custom paper length (8.5" wide X 7" long) Now here's the wierd part... IF I switch back to the win95 driver, re-accept the custom paper size, print a test page (in NLQ of course), switch back to the generic driver, re-accept the the custom paper size, switch the printer to normal (non NLQ), and print it works fine with the custom paper size and non-NLQ mode until the next time it needs to print. The printer remains ON 24/7, so its not reseting itself. It just seems that with the Win95 driver there is no way to set it to print in anything but NLQ AND the generic driver refuses to keep the custom paper sizes in memory. Anyone seen this before? Never came accross this myself. I may just end up sending this thing back and getting an Epson or someting else." AND THERE IS THIS: "This is like going back to the dark ages....most of those old impact printers had dip switches to set things like default print quality. Additionally, Oki's usually came in two 'flavors'--plain Oki and IBM Oki. It's important that you install the correct driver between the two options..." Anthony

It would be unusual for all the colours to go out of alignment. Its probably just black but to re calibrate them all just turn of the power. Pull out all the ribbon cables to the four print heads. Make sure their ends touch no metal parts. Close the cover carefully and turn the power back on. You will hear no sounds then after intitializing you will get a fatal error 13-. Turn the power off and reconnect the ribbon cables. Turn the power back on and recalibration will take place (you wont see it happen) and all will be well.

I would think you have broken ribbons cables to the cyan and magenta LED print heads. As all the heads are the same I suggest you swop the black and cyan print heads around and see if cyan prints and black does not. That will prove is the print heads are ok. If they are then the ribbon cables need replacing or they are dirty at the heads. It could be just a case of unplugging them, clean them, then plug them back in again.

Basically the machine does not recognise the image drum. You maybe using the Xerox equivalent which of course wont work. Replace the drum with an OKI one and it should work even though its really a Xerox printer.

All you need to do is unlock the scanner. Just open the flatbed cover and on the left edge is the slider for the lock. Slide it towards you and that's it unlocked.

Never use spirit to clean rollers. Just fairy liquid and water. All the roller gets is grease from the paper on it. Fairy liquid is the best degreaser. Alcohol will soften the rubber and it will work short term and then the roller is finished and will need replacing.

Is this a networked printer? You may need to reload the print driver into your computers. Most printers are generic enough that computers will recognize them and automatically install the drivers. Sometimes you need to go to the manufacturer's website and download the drivers you need.

Sometimes the fuse in the drum blows but the printer does not register it so it still thinks a new drum is required. You can find new fuses on ebay. Its cheaper than buying another new drum. Also put a new drum in with the power turned off. Once the lid is closed then turn the power back on and then the fuse will blow at the correct time.

Open the rear cover and in the centre of the curved black guide you will see a small black lever with a silver spring on it. this is a arm to the jam sensor. check it moves freely and returns to its upright position. If ok the blow air under it into the actual sensor. Check the pickup roller is not smooth. If it is its rubber tyre can be rotated so the good part touches the paper.

The thin lines are caused by a worn out drum. Remove each drum in turn and look at the surface. It maybe hard to see the scratches and if so then send solid blocks of the primary colours one at a time and that will prove which drum is at fault.

Agree with pcfixup.ca. Remember the software on a pc overrides the printers actual settings.

you may have to make another tray the default tray then you select the paper size to print on and put the size paper in the default tray
