LQ 300 +2 auto pause during printing

This is a feature provided by the manufacture to protect the print head overheat for small dot matrix printers. Here giving printer head connection diagram, the last two row have temperature sensing (thermister) connection pin 1 to 1. If the thermister is faulty in the print head the printer will auto pause abnormally. Check the printer with compatible / EPSON recommended print head. These kind of small printer only for POS printing not for continues printing. 2_17_2012_8_31_04_am.jpg

I have a brother HL-4040cdn printer and the past couple days I'm getting small dots on the printed pages????


If the dots are random and can be scrapped off with your finger nail then they could be coming from a dirty fuser assembly. If the dots are random, but can not be scrapped off then you could have a bad toner cartridge that is letting toner get by it's recovery blade. If this is the case then another cartride should take care of the problem.

My kyocera color copier has blue dots going across the page when I make color copies.

I beleive you listed your question under the wrong model machine. The CS-4035 is a black and white copier and should not be making bluse dots. Verify the model number please.

It prints three dots on the left side of the page every time.

These dots may be called as "Garbage Valley"
This means ur printer has got lots to print but it was stopped due to certain reason.
I'll ask u to go through ur printer manual & print atleast 5 pages of garbage valley & while u do this, i'll ask u to reinstall ur printer driver.
Hope it works out.

Red dots on left of page

You need to measure the distance between two dots (In milimeters if possible). After that I may be able to determine what is causing the problem.
