OKI MicroLine 420 Matrix Printer - Answered Questions & Fixed issues

As the alarm is on and steady then you most probably knocked the change lever into a position where it detects no paper loaded. The easiest way to check is to load your paper and move the change lever until the error lamp goes out!

The machine needs to be cleaned.

low on ink. Need to replace

I want to be able to print more than 1 copy at a time with out having to adjust the start up line after every Print. It was working fine until I swapped out computers and I even used the disk to install it and I have tried everything and it will not work

just saw this yesterday. remove the top rear paper guide. on the left side between the tractor feed and the input slot for the paper, there is a sensor flag that pivots. check for paper scrap caught under the flag. it prevents the flag movement, causes a paper out alarm.

Catrdge problem or head problem

use the -r print option in the name of the printer
ie. "printername -r"

Hi I am Steve lets get you some help
Based on your description you are running the printed pages or the usage report on a schedule and you are asking the printer to print it out. you need to go into the management software and in the printed pages report either turn it off completely if you don't need the information or make sure it is set to email this info only not the print it.

Goto the Oki website and download the drivers for your printer from there -

On the right top side of the machine is a knob, just above the big knob on the side. Here you can select the paperpath. Make sure this knob is in the correct position.

You have a faulty print head the pins are not fireing you need a replacement print head.

Go into your print quene and tell it to stop the job. You do this by bringing up your printer software and clicking on print quene.

You can download the manual from your Okidata weblink below:

This would be the print head pins not moving forward or the ribbon bunched up at the top.

Yes, I contacted my IT Department and they were able to make a setting change via our Network which solved the issue.

Thank You for your time.

You can change the dfont size from the menu, but that setting afects the entire page of print. You different size fonts are controled from the codes sent to the printer from the software. Recreate the document, or create a document with a sample of that small print and see if the printer prints it.

Press & hold shift then press sel to enter menu mode. Press group until the group you wish to change appears in the first column. Press item until the item you wish to change is in the second column. Press set until the setting you want appears in the third column. Press and hold shift then press sel to exit & save your settings.

The default page sizes are; 11", 11-2/3", 12", 14", 17", 5", 3", 4", 5.5", 6", 7", 8", 8.5".

I think its a fuse?
