Paper Jams
The majority of paper jams are caused by the paper, not by the photocopier.
Paper is very sensitive to moisture and heat, and this can affect how the paper performs in
the machine.
The most common jam is when printing or copying double sided (also known as ‘duplex’
printing)
If the paper contains moisture, the heat inside the photocopier quickly evaporates any
moisture contained in the paper, causing the paper to curl.
When the machine takes the paper back inside to print on the reverse, the curl then makes
the paper jam.
Hint & Tips

Always try to “fan” the ream of paper before placing it into the paper tray. (Fanning
paper can eliminate the risk of two pieces being stuck together and can also reduce
static)

Do not store paper for your printer in warm, humid or damp conditions

If the machine jams, please check that the paper in the tray is not damp or overly
curled. If it is, replace with new paper

If your machine hasn’t been used for an extended period (e.g. over the summer
break) please check the paper in the tray isn’t damp or curled before using.
