Duplexing, or double-sided printing, can be a huge time-saver—until you hit a jam. When your photocopier encounters a duplex jam, it’s often down to either incompatible paper or a leftover piece of paper still stuck in the duplex path. Here’s how to tackle and prevent duplex jams effectively.
Why Does Duplex Jamming Happen?
- Unsupported Paper
Duplex printing requires specific paper types, sizes, and thicknesses to work smoothly. If you’re using paper that’s too thick, too thin, or the wrong size, it can struggle in the machine and cause jams. - Paper Still Stuck in the Duplex Path
Duplexing involves several complex twists and turns as the paper goes back for a second pass. Sometimes a small piece of paper gets left behind and causes the next sheet to jam.
Quick Fixes for Duplex Jams
Here’s how to get rid of that pesky jam and prevent it from happening again:
- Use the Right Paper
Stick to paper types that are compatible with duplex printing. Plain paper and recycled paper generally work well, and thicker media can sometimes be used, but only if specified by your copier’s guidelines. In the printer driver settings, be sure to select the correct media type before you start a duplex job. - Avoid Mixing Paper Types
Mixing different types of media—like plain paper with thicker or speciality media—in the same tray can cause jams. Ensure the tray holds only one type of compatible paper for reliable duplex printing. - Avoid Duplex on Certain Media
Duplexing isn’t suitable for all paper types. Avoid using envelopes, labels, stationery, postcards, blank media, and any single-sided speciality paper for duplex jobs. These types can jam or damage the machine during double-sided printing. - Double-Check the Duplex Path
If the jam message doesn’t go away after removing the paper, open the duplex area and carefully inspect for any remaining bits of paper. Use a flashlight if necessary to spot any tiny, hidden scraps.
Tips to Keep Duplexing Smooth
To make duplex jams less likely in the future, consider these small habits:
- Keep Your Paper Dry and Flat
Paper that’s been exposed to moisture or is slightly curled can cause jams more easily. Store your paper in a cool, dry place to keep it in good condition. - Set Paper Guides Accurately
Make sure the guides in the paper tray are set correctly to fit the size of the paper you’re using. This ensures each sheet feeds in without skewing, reducing the chances of a jam.
These tips should help you clear duplex jams and keep double-sided printing working smoothly. If jams continue despite using compatible paper and proper settings, it may be time to contact a technician for a deeper look at the machine’s duplexing mechanism.
