Short version:

If you have an Epson inkjet printer that is equipped with a maintenance box but you now find your printer has a “Service required” error that isn’t fixed by replacing the maintenance box, then it’s likely your printers platen waste ink pad counter is now “full”. This counter may be resettable using the WICReset app.

Read below for more details and find out how to check for whether your printers platen pad can be reset by the app.


So, Epson has been designing a lot of printers lately that have a user replaceable maintenance box which is basically a waste pad holder with a chip (a sort of cartridge that absorbs ink rather than supplying it). So you never have to worry about waste ink counters or replacing the waste ink pads any more, right…! Right??!!

Maintenance Box = No More Waste Ink Problems?

Spoiler alert: Erm… Not quite!

The introduction of maintenance boxes, as a replacement for the old practice of building waste ink pads into the printer, and  tracking the waste via an internal waste ink counter, is definitely an improvement for the average end-user as it means you no longer have to fit an external waste tank or get messy changing out the waste pads. If you’re particularly keen you can even purchase chip resetters that reset the chips, and replace the pads in the maintenance box yourself so you can re-use your maintenance box.

And while the chip does take over from the main waste ink counter, it doesn’t deal with all of the waste ink that your printer generates.

Introducing the Platen (Waste Ink) Pad

The platen pad is the wide waste ink pad that sits along the width of the printer, under the path that the printhead takes when your printer is printing. Its role is to catch any ink that the printer dumps over the edge of the paper, particularly borderless prints.

Now, this sort of waste ink is miniscule and you’d struggle to measure it in microliters, let alone see it, so this waste pad is thinner and has much smaller capacity than the maintenance boxes hold. However, if your print usage requires you to print a lot of borderless prints you are going to hit this problem eventually.

Just as a quick point here. If you don’t use your printer to do any borderless printing it’s unlikely that you will experience this platen pad related “service required” error (on your maintenance box equipped printer) but we do still get occasional calls from printer owners who hit this error without doing much if any borderless printing. So it is still worth knowing about the problem, and the solution, so you don’t get caught out.

Introducing the Platen Pad Waste Ink Counter

Yes, you guessed it, the platen pad has an internal waste ink counter. This counter is not controlled by the maintenance box chip, nor does Epson provide any means for you to reset it yourself.

One of our contacts spoke to a first line support tech in the UK asking for a quote to get this resolved for a SC-P900 and the price offer was a cool £900 (GBP).?!! (We’re not kidding!).

Resetting the Platen Pad Waste Ink Counter

The good news here is that the developers of WICReset have anticipated this particular problem and have already added a function to reset the platen pad waste ink counter for a number of printers (with maintenance boxes) that are affected by this issue so it’s worth downloading the WICReset app from* and checking whether your printer is compatible and covered by this feature under the “Supported models” tab.

Checking if the WICReset will reset your platen pad waste ink counter

If it is, you can rest assured that you have a solution without needing to re-mortgage your house or take out a loan to pay for the crazy service centre prices.

*The Printer Potty WICReset app is currently feature limited and doesn’t include this function but will in the future.

What About The Pads

When it comes to the physical waste ink pads themselves we don’t currently have a recommended practice as the issue doesn’t crop up too often. But from the few times we’ve tackled this ourselves, we just used some absorbent padding material (like nappies, ladies panty liners or similar) to soak up any excess moisture in the platen pad by leaving them absorbent side down, in contact with the platen pads, overnight. This seems to work quite well and is only needed every few months depending on just how much borderless printing is being done.

Physically replacing the platen pad is not something we’d necessarily recommend but if you can get the correct part you may decide to try.
