HP Colour CM2320FXI in london Printer with intermittent banding on prints

hp-color printer

The customer contacted us with this strange fault with their HP Colour laserjet CM2320 printer, because banding would occur on print outs intermittently. Not every print would produce the strong horizontal lines with multiple colours, as shown below is an example of the marks on the prints.

After carrying out a diagnostic assessment on the printer and including colour print testing. My 1st thought was that it could be a fault with the formatter board, although I could see some of marks on the prints that where directly related to worn or faulty toner drum unit so we replaced all the toners and tested the printer. Printer tested all OK.

The customer was using compatible toners which can save customers a lot of money on their printing costs but not all compatible toners are the same and they vary in price. I have no problem in recommending compatible toners but I do recommend following the advice below. If you buy compatible toners for your printer, you should avoid buying the cheapest on the market, especially if your business solely relies on that printer. Some toners are just old cartridges refilled with toner, others are clone’s. The final option of compatible that have been remanufactured from used HP toners and refurbished the worn parts are in full working order. Buying the cheapest toner is ok as long as you accept the odd failure in prints. Always have a spare set of toners on site for your printer if it is mission critical always have a spare set of original toners onsite. 

Check with your supplier what the returns policy is. We promise that we will return any faulty toners with more than 20% life left with no fuss all be ask for is a supplies page to be sent. This will allow you to avoid expensive printer repair bills for faulty toners use a supplier that will. Return faulty toners without fuss and service your printer for free once a year like us if you use at least 2 sets of toners per year.

Excellent customer service Contacted them about fixing a dead HP printer but decided it was quicker to replace it as our business can't function without one. Andrew in service recommended a Brother machine which is perfect for our requirements and Jeremy in sales arranged delivery by 10:30 the next morning (it arrived at 9:30!). I was in a tight spot and both of them did their utmost to help. I shall definitely be purchasing from them in future and highly recommend Diamondsource Ltd. Thank you.
