4. Running "Long Grain" Heavyweight 1 or Coated 1 papers:
• 17 inch/431.8 mm or larger Heavyweight 1/Coated 1 papers (105-176 gsm) may
sometimes be cut "Long Grain." HeavyWeight 1/Coated 1 papers cut this way will
be nearly as stiff as HeavyWeight 2 papers, and will likely jam if fed in the
HeavyWeight 1 or Coated 1 modes because they will be fed face-up into the
inverter.
• Looking at the paper size on the ream wrapper can identify Long Grain paper. The
second number in the size indicates the grain direction. For example 11 x 17 in./A3
indicates the grain is in the 17 inch/431.8 mm direction. This paper is Long Grain.
17 x 11 in./A3 indicates the grain is in the 11 inch/279.4 mm direction. This paper
is Short Grain.
• HeavyWeight 1 or Coated 1 Papers labeled 11 x 17 in./A3, 12 x 18 in./304.8 x
457.2 mm, 13 x 19 in./330.2 x 482.6mm, etc. are Long Grain and should be fed
in HeavyWight2/Coated 2 mode. If your paper is not supplied with a wrapper,
check with your paper supplier about the grain direction.

Preventing Fuser Damage
1. To avoid 11 in./279.4 mm lines and wear marks, you may require the use of two
Fusers - one when running 8. 5x 11 in./A4 stock, and the other when running 12 x 18
in./304.8 x 457.2 mm or larger stock. This is especially true for the Graphic Arts people.
2. Image quality defects such as marks or spots will occur every 110 mm/4.3 in. on the
prints if the Fuser roll is damaged. Defects which occur every 98 mm/3.89 in. indicate
a damaged Fuser belt.

Miscellaneous hints and tips

• System requirements messages (for example, "Order Waste Toner Container," "Hole
Punch Waste Container Full") may occasionally be blocked by the current UI screen.
Close the Job Status screen and open the Machine Status/Supplies screen to check
consumable status.
• If the machine stops running mid-job, or does not begin printing after a job is
submitted, check the Machine Status/Supplies screen to determine if supplies need
to be replaced. The system will stop if sufficient supplies are not available for a
