How to Keep Your Copier Clean: A Simple Maintenance Routine

A clean copier produces sharper copies, misfeeds less often and is less likely to need a service call. Most everyday print-quality complaints, from gray streaks to speckled backgrounds, start with dust, fingerprints or toner residue rather than a broken part.

Copiers work by xerography, a process that uses static electricity, light and heat to transfer toner onto paper; you can read a fuller description in this overview of xerography. Because the process relies on static charge, copiers naturally attract dust and paper fibers. Over weeks of use, that debris builds up on the glass, rollers and paper path.

A simple routine that takes a few minutes each week keeps that build-up under control. It also helps you spot real problems early, because once the obvious dirt is gone, any remaining marks or noises point more clearly to a part that needs attention. If you are not sure what a term on your machine means, our guide to useful copy machine jargon explains the common ones.

Cleaning also protects your investment. A copier is one of the most heavily used machines in an office, and small habits, such as keeping drinks away from the machine and closing covers gently, prevent many of the problems that lead to service calls.

You can safely clean the scanner glass, document feeder, feeder rollers, paper trays, exterior and control panel yourself. Internal imaging and heating parts should be left to a technician.

The table below is a practical starting point. Always check your copier's user manual first, because some manufacturers specify particular cleaners or tools for their machines.

Turn the copier off and unplug it before cleaning anything beyond the glass and exterior, and wait for internal parts to cool.

Lift the lid, apply a small amount of glass cleaner or water to a lint-free cloth, and wipe the platen glass and the narrow scanning strip used by the document feeder. Then dry both with a clean section of the cloth.

The scanning strip, sometimes called the slit glass, is the narrow strip of glass beside the main platen that the document feeder reads originals across. Because originals slide over a fixed point on this strip, even a tiny speck of correction fluid or dust shows up as a continuous line down every page fed through the feeder. That is why lines appear on feeder copies but not on copies made from the main glass.

• Use a soft microfiber or lint-free cloth, never paper towels, which can scratch and leave fibers.
• Apply cleaner to the cloth, not the glass, so liquid cannot seep under the glass edges.
• Wipe the white backing on the underside of the lid or feeder too, since marks there can appear on copies.
• Let originals with wet ink, glue or correction fluid dry fully before copying them.

If lines remain after cleaning, run a test copy from the main glass and one through the feeder to see which path is causing them.

Wipe the rubber rollers with a lint-free cloth slightly dampened with water, rotating each roller so you clean the whole surface, then let them dry before use. Clean rollers grip paper properly and reduce misfeeds and double feeds.

Pickup rollers are the rubber wheels that grab the top sheet from a tray or document feeder and pull it into the machine. Over time they collect paper dust and become glazed and slippery. When that happens, the copier may pull several sheets at once or fail to pick up any sheet at all.

Open the document feeder cover to reach its rollers, and pull out each paper tray to access the tray rollers, following the diagrams in your manual. Avoid alcohol or solvent cleaners unless the manufacturer approves them, because they can dry out rubber. If rollers are cracked, shiny or worn smooth even after cleaning, they likely need replacement. Our guide to preventing paper jams through better paper storage and handling covers the paper-side causes of misfeeds.

Document feeder rollers deserve the same attention. Because originals often carry staples, sticky notes and ink, feeder rollers can pick up residue quickly, so check them whenever pages start to skew or stop partway through.

Never spray liquid into or onto the copier, touch the drum surface, use abrasive materials, or reach into the machine while the fuser is hot. These mistakes can cause damage that cleaning cannot undo.

• No sprays: liquid can seep under the glass or into electronics.
• No abrasives: scouring pads and rough towels scratch glass, and scratches print as permanent marks.
• Don't touch the drum: skin oils and scratches on the light-sensitive drum show up on every page.
• Respect the fuser: the fuser heats toner to bond it to paper and stays hot after the machine is switched off.
• No household vacuums on toner: fine toner particles can pass through ordinary filters, and toner dust can be a fire hazard in standard vacuum motors.
• Don't force covers: open panels only as the manual describes.

A drum is the light-sensitive cylinder that holds the toner image before it is transferred to paper. On many machines it is a separate consumable, so damaging it means a replacement part.

Wipe small amounts of loose toner with a dry, lint-free cloth, using cold water if any gets on skin or clothing, and leave larger spills inside the machine to a technician with a toner-rated vacuum. Warm water can set toner into fabric.

Toner is a fine powder made mostly of plastic resin and pigment that is melted onto paper during printing; this article on toner explains its makeup. Because the particles are so fine, they spread easily and cling to surfaces.

Most spills happen when a cartridge is removed or shaken carelessly. Replace cartridges over a sheet of scrap paper, follow the replacement instructions shown on the panel, and seal used cartridges in their packaging. If you notice toner dust building up inside the machine or loose toner on printed pages, the cartridge or waste toner container may need attention. Stock replacement cartridges and drums from our toners and drums collection so a swap never has to be rushed.

Call a technician when problems persist after you have cleaned the glass, feeder and rollers, or when the issue involves internal parts such as the fuser, drum unit or laser assembly. Repeated jams, grinding noises, smeared toner and error codes that return after a restart are all signs of a mechanical issue.

Smudged or smeared toner that wipes off the page usually points to the fuser. Repeating marks at regular intervals down the page often come from a drum or roller. Faded or uneven prints can mean low toner or a worn imaging part. Our guide to common copier frustrations and their solutions walks through more symptoms.

For commercial copiers, a service plan can make repairs more predictable. Browse extended warranties for coverage options, see our service network page for how service works, and visit our support page for help with an existing purchase.

A short weekly and monthly routine handles nearly all user-level cleaning. Pin this list near the copier and assign one person to own it.

1. Weekly: wipe the platen glass and feeder scanning strip with a lint-free cloth and approved cleaner applied to the cloth.
2. Weekly: wipe the white lid backing and the exterior control panel.
3. Monthly: switch off and unplug the copier, then let it cool before opening any covers.
4. Monthly: remove paper from each tray, wipe out dust and scraps, and reload with fanned paper.
5. Monthly: dust the vents and fan grilles with a dry cloth or soft brush.
6. As needed: clean feeder and tray rollers with a slightly damp cloth when misfeeds start.
7. Record recurring problems, error codes and the date, so a technician can diagnose them faster.
