Paper specifications for ECOSYS printers
In order to help you choose the best paper to use in your laser printers we have created this summary highlighting the key points.
Paper sizes
The standard cassettes in the FS-400, FS-600, FS-680, FS-800 and FS-1000 can be adjusted to use A4, A5, B5, letter and legal size paper.
The optional paper bin (PF-8 for the FS-400, PF-16 for the FS-600 and FS-680, PF-17 for the FS-1000) supports the same paper sizes.
The standard cassette in the FS-1700/+ and FS-3700/+ can be used with A4 paper only. Internal paper cassettes can also be purchased for use with the letter, B5 and A5 paper sizes.
The standard cassette in the FS-1750 and FS-3750 can be adjusted for use with A4, A5, B5, letter and legal size paper. The paper tray can also be adjusted to fit any paper size between A4 and A5.
The standard cassette in the FS-5800C and FS-5900C support A4 paper. Cassettes are also available for legal paper size.
The FS-6700, FS-7000/+ and FS-9000 printers support all of the above sizes as standard including A3, B4 and ledger.
Paper size guide:

Name of Paper Size |
Actual Size (cm) |
| A4 | 21 x 29.9 |
| Letter | 21.3 x 27.6 |
| Legal | 21.3 x 35.1 |
| B5 | 18.2 x 25.7 |
| A5 | 14.8 x 21 |
| A3 | 29.9 x 42 |
| Ledger | 27.6" x 42.7 |
Weight (measured in grams per square metre)
When printing from your printer’s internal tray, the weight of paper you can use is 60 to 90 gsm.
Using a straight-through paper path (i.e. from the manual or by pass feed and out the back of the printer) the maximum weight is increased to:
135 gsm for FS-400, FS-1500, FS-1550/+, FS-1600/+, FS-3400/+, FS-3600/+, FS-6500
163 gsm for FS-600, FS-680, FS-800, FS-1000
200 gsm for FS-1200, FS-1750, FS-1800, FS-3750, FS-3800, FS-7000/+, FS-9000
The FS-1700/+, FS-3700/+, FS-1750 and FS-3750 can have a replacement internal cassette to support heavier weight A4 paper (90-135gsm).
Using a duplex unit on a model requires paper to be within the weights shown in the table below – using lighter or heavier paper could result in serious jams.
| Duplex Unit Model | Paper Weight (gsm) |
| DU-1 | 70-90 |
| DU-20 | 70-90 |
| DU-21 | 70-90 |
| DU-25 | 70-90 |
| DU-30 | 60-90 |
| DU-31 | 60-90 |
Grain
Paper used in laser printers which feed paper short edge should always be long grain (all laser and copier grade paper is long grain). If short grain paper is used in any laser printer then the paper will curl badly and will cause jamming if you are duplexing. The FS-7000/+ and FS-9000 feed paper is fed long edge on and can therefore use A4 short grain.
NB: Many people produce A5 paper by cutting long grain A4 in half. This makes the A5 effectively short grain which will cause problems. When purchasing A5 paper it is important to ensure that it is also long grain.
Smoothness
If the paper has a textured surface (such as laid or hammered paper) the print may be patchy or the toner may not adhere to the paper in the depressions.
Glossy paper or coated paper may suffer from grey background print.
Storage
Paper should be stored flat, at room temperature and only removed from the moisture proof wrapping when ready for use. If it becomes exposed to the air even for a short time the paper will absorb moisture. This could result in high levels of paper curling.
Envelopes, labels and transparencies
Labels, envelopes and transparencies can be difficult materials on which to print.
You can minimise the risk of damage to your printer by ensuring you are using media suitable for use with laser printers, within the printer’s specification and using a straight-through paper path.
NB: Your printer warranty does not cover any damage caused by the use of labels.
Labels
To minimise the risk of damage, laser labels must be fed from the manual or multi-purpose feeder providing a straight-through paper path. Label sheets should be fed through the printer only once and only complete A4 sheets should be used.
Envelopes
The printer can print on envelopes using paper with a basis weight of 60 to 79 g/m2 (16 to 21 lb/ream). Envelopes must be manually fed.
An envelope is a more complex object than a single sheet of paper. For this reason, it may not be possible to obtain consistent print quality over the entire envelope surface.
Many envelopes have a diagonal grain orientation. This orientation is more likely to wrinkle and crease on its way through the printer. Before purchasing envelopes for use with the printer, test a sample to verify the envelope’s suitability.
Do not use envelopes that have an encapsulated liquid adhesive.
Avoid long printing runs consisting of envelopes only. Extensive envelope printing can cause premature printer wear.
To avoid jamming due to curled envelopes, do not leave more than approximately 10 printed envelopes stacked in the paper trays during multiple envelope printing.
OHP film
You MUST use OHP’s designed for use in a laser printer. Other types may melt when they come into contact with the fuser.
We recommend 3M CG3700 and 3M CG3710 for use in our colour printers (FS-5800C and FS-5900C).
OHP’s must be fed into the printer the correct way up to avoid jams and damage to the printer.
Carbonless Paper
Carbonless paper should not be used in your Kyocera Mita laser printer because the pressure applied by rollers during printing may cause the carbon capsules to burst resulting in poor print quality and in some cases damage to the printer.
