Yes cleaning the LED heads do make a difference. If they are even the slightest bit dirty your output will be affected. However the quality of the prints on these printers are not very good. I have 3 of them and all of the product subpar quality (right out of the box) especially with lighter solid background colors.

On card stock (especially coated card stock) you'll notice shading on the entire page. Again this happened out of the box on all three of my printers. I researched this and read that it was an effect of the LED technology.

Also if you look closely at your prints you'll notice that there are bars in your print. These bars look like there could be something wrong with the LED matrix...

I just installed a magicolor 7450 II and man what a difference. No shading, perfect picture quality, and larger banner printing (12" x 47") Of course the price tag is a lot more ($3k)

2 Missing ink black streaks


Check the dev unit for missing lines. Also clean the laser glass with the supplied cleaner pad - though if the problem were caused by toner on the lens, there would be gaps in ALL colours.

Check the dev units first. You can also do a stop test whilst a full colour test image is half way through printing and see if the lines are missing off the image on the PCU as well.

Print quality Epson C1100


It sounds as though a cartridge is faulty. To determine which one, the easiest way is to run a page of text/block of colour through in yellow then cyan then magenta. which ever page comes out with the streaks on it will tell you which cartyridge to ditch and replace. Hope this helps Cops Pete@wedotoners.com
