Clean B432 LED Heads
This knowledge base article shows you how to Clean B432 LED Heads in your OKI printer, vital when having Print Issues with your components. We also recommend regular cleaning of the LED’s, for example while replacing Toner Cartridges or after printing 500 plates. The instructions below assume you are directly facing the front of your Trade Mono printer.
Always ensure your printer has cooled down before carrying out any cleaning. To reduce cross contamination, cover your exposed image drum with a clean cloth or large sheet of paper.

Before you can clean your print heads you have to get to them, on the B432 they’re under the Top Cover. So start by opening up the top of your printer. Press in the round button, indicated on the image above, to open up your printer. Now you can hinge it up fully to reveal the printer innards and the Toner & Drum Unit close to the front.

The B432 LED Heads are connected to the printers top cover (A) as shown on the image above. On lowering the top cover their White Mounting lowers into position above the fixed Fuser Unit. It can be easier to clean the heads if you lower the top cover slightly, since it provides more hand room.

Having Trouble? – Check Conditions
If you’re having to clean your printer heads a lot, you may be using the machine in less than optimal conditions. Remember this number plate printer requires a warm, dry and dust free environment, like an office. Store your consumables in a similar location and keep them in their packaging until required.
