Tip & How-To about Office Equipment & Supplies

Okidata Dot Matrix Printers So, the one thing that no one ever pointed out is that Okidata printer head jewels get lubricated VIA the ribbon. You MUST use at least 50 to 70% Brand name original cartridges, or suffer premature print head wear. Once the printed character becomes blurry, get a REMANUFACTURED head, with the oiling wick. This lets you use all the cheap ribbons, by lubricating the jewels directly. When you are all finished, enter the menu of the printer and play with REGISTRATION. Often you can make a crisper print by tweaking this setting.

I the printer is not printing the top of letters instead it is dragging that ink across the paper

Look at the print head for jewel failure. AFTERMARKET ribbons lack requried lubrication for this style of printer. If you see wear, replace the head. There are remanufactured heads available that have a lubrication wick installed that helps this issue.

printing quality is very poor

The print quality of dat matrix printers depends upon the printer ribbon. If the ribbon is old or worn out then the print will be very light. In this case replace the ribbon.
Dot matrix printers are very old technology and I suggest you get a Inkjet printer or a laser printer.
Dot matrix printers cannot match the print quality of Inkjet and laser printers.

Print is very faint shortly after changing ribbon.

The head may not be close enough - most dot printers have an adjustment for paper thickness (1-5 pages) check this. Also the head could just be going bad - they loose length after beating on the bar over years. Another thing is the bar (or plattem) gets worn down and has a grove in it over time. Lastly the ribbon maybe junk - they sit in a whearhouse for years and get dry. Sorry - very generic answers.- but true
