The most frustrating copier fault is the one that goes away and comes back. The jam you cleared yesterday, the line down every page that faded after a restart and returned, the code that cleared itself twice and stuck the third time. In our experience these are rarely bad luck. A repeat fault almost always has a cause that a restart does not reach.
Repeat jams: rollers and paper
Pick up, feed and separation rollers wear smooth with every sheet they handle. As their grip goes, the machine starts to misfeed, pull two sheets at once, or skew a sheet so it jams further along. Clearing the jam removes the sheet, not the cause. If one tray jams and the others do not, the rollers for that tray are the first suspect.
Paper is the other half. Paper that has been left open in a humid room curls as it passes the hot fuser and jams near the exit; paper in a dry, heated office builds static and double feeds. Keep reams sealed until they are loaded, use the weight and type the tray is set for, and fan the edges of a ream before it goes in.
Streaks and marks: drums, developer, transfer and the scanner
A line on every page that is in the same place each time points at something that turns: a drum, a developer, a transfer belt or roller, or the fuser. Marks that repeat at a regular gap down the page can even tell a technician which one, from the distance between them. Lines that appear on copies but not on prints from a computer point at the scanner glass or the document feeder's scanning strip instead, which often just need a clean with a soft, dry cloth.
Fuser codes that keep returning
Fusing units run hot by design and wear on a page count. Most brands lock the machine on a fusing fault for safety, and on several (Ricoh level A codes, Canon fixing assembly errors, Sharp H codes) the code is held until a technician clears it in service mode. Restarting over and over does nothing for the cause, and the fusing area should never be opened by hand.
Codes after storms, updates or a move
Controller and hard drive codes often follow a power event: a storm, a brief outage, or the machine being switched off at the wall mid job. Scan to email that stops working overnight is nearly always a change on the network side, such as a new mail setting or password. Tell the service desk what changed recently; it points straight at the cause.
Life parts nobody fitted
Copiers are built around parts meant to be replaced at a page count: fusers, drums, developers, transfer belts, maintenance kits. Most machines say so on the panel when one is due. Pressing on past those warnings is how a machine that was printing well on Friday stops on Monday morning.
How to stop it
Planned servicing is the answer to most repeat faults: the paper path cleaned, wear parts checked against their page counts and fitted before they fail, and the things that are starting to drift put right. It is what a service agreement is for. See photocopier servicing in Brisbane, in Sydney and in Melbourne, or managed print for a whole fleet.
The brand pages set out what wears first on each make, and what its codes mean: Konica Minolta, Sharp, Canon, Toshiba, Kyocera, Ricoh, Fujifilm and HP.
