Question about OKI MICROLINE 520 Matrix Printer

2 Answers

Double Printing We use Syspro as our financial system. We have a dedicated check printer OKI 520. To print the Remittance we switch to the other printer, OKI 5520 after the checks printed. We now have the problem that it duplicates the Remittance print. We did not have this problem when the same printer was used and the stationary changed in between( The OKI 520 as only printer) Could the error be because we switch between the printers? Syspro's option to print duplicate remittances is not selected.

    we still have the problem. Checked the Parameters and Remittance settings. Next step is to print to 1 printer as in the past and see what happens.

Using Win7 - switches to NLQ mode every time regadless of driver used - Okidata Elite (Microline) 520, Okidata Elite (IBM) or Okidata 520. Tried changing drivers - none other available for Win7. With the...

This is a SNIP of a rather LONG FIX:

Found here:

"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."

"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..."

How do you reset the Oki printer, we have a large printjob gone to printer memory which we want to cancel

turn printer off and delete print job from printer folder on computer. a small printer ikon should be visible on bottom right corner of windows screen. double click on this and delete print jobs in the box.

OKIDATA Mirocline 520 is printing off-center

I assume you've checked Page setup in the particular software you are using. It seems unlikely, but perhaps something is awry with the printhead home position sensor. This device is on the left side of the printer, and essentially sets a reference point, and the printing start position is counted from this reference. Sometimes this sensor is an optical device, other times a mechanical switch. The latter would be more apt to cause problems. If another tech has a better solution, say on!
