You should clean the printer every six months (or after
about 300 hours of operation).
1. Turn the printer OFF.
2. Remove the paper from the path.
3. Open the access cover and remove the pull-up roller
assembly.
4. Use a clean, dry cloth to dust the area around the
carriage shaft and platen. Be sure to remove any loose
particles of paper.
5. Reinstall the pull-up roller assembly.
6. Close the access cover.
Never use solvents or strong detergents on the
cabinet — they could damage the housing.

Horizontal print gaps on ml184+


Hello,

The most common cause of missing sections in the letters is a bad print head. These types of printers (Dot Matrix) create the print with the print head which has a line of small pins called hammers that are activated by an electromagnet. Each pin has its own hammer. If the electromagnet fails or you have something jamming the hammer then it will not move to strike the ribbon and make the image or letter. You can get a replacement print head online for about $15.00, the part number is 50063802. Here is a picture of what the print head looks like. :

Pages print with a line thru all the text. They aren't underlines, but have an actual line printed over the text. How do I change this?


Hello,

It's called overstrike.

Try send a print out from another application. If result is same, then print a self test page. Still the same, then replace cartridge.

Otherwise, head needs service/replacement.

However, if self test print out look good then you should check printer preferences.

good luck

Sounds like the print head is at fault. The print head is actually a vertical line of small wires that move in and out to form the dots as the head moves across the page printing one row of characters at a time. One of the wires has failed. While it is possible that cleaning the print head with contact cleaner will resolve the problem, it might be time to replace the print head, or likely buy a used working replacement printer at less money than the cost to repair.

Try to perform an offline test print using your printer alone
To do this, power off your printer first
Press and hold the LF/FF button on the printer panel then power on. The printer will perform its own printing ( lines of pattern )
If it does it without problems ( no MENU lights came on ) the printer should be OK. If not try replacing the printer main control board.

Hope this helps

My Brother MFC-465CN is printing text with alignment off and double text.


My Brother printer MFC-465cn is doing the same thing. I have workaround / worked-around it by disabling bi-directional printing. Then print is clear. It's as if the head is shifting an irregular amount on the opposite direction, like the head is loose.

Same for copies. If I use the PC interface to make copies, I can set the copy printing to be mono-directional, then copies are clear.

I am trying to hook my printer up to my new computer and the disk I have is not working. i do not have a cd for microline 590 elite dot matrix drivers


The drivers should be on the company website, if these are not working for you the generic text driver in Windows will work for text only printing. If you do graphics or formatted invoices, etc. on the printer Epson and Okidata both make pretty generic print drivers that should work for a microline printer.
