ACCEL-7450 Problem Solving 1. Printing misaligns toward the bottom of my form (skews). Ensure the LEFT paper guide is squared by sliding it all the way to the right against the paper rack stop. Take your time in properly aligning the form, being sure to slide it in until it stops against the feed rollers. The printer beeps up to 3 times (default is one beep). 2. Frequent Paper Jams. Flatten any curl at the leading edge of the form by folding it in the opposite direction.
ACCEL-7450 6. My printer sometimes asks for a second form when there is none. The printer is misinterpreting left over control characters as more to print. Press the Online key to clear. Press ALT+RESET to clear any pending data. 7. The message PAPER JAM appears, although paper is not jammed. The paper jam sensor on the tractor assembly may not function properly if exposed to direct light or sunlight. Adjust the location of the printer so it is not exposed to excessive light.
ACCEL-7450 12. Incorrect characters printed. Wrong emulation. Verify the setting in printer menu item #15 EMULATION is compatible with the print data. The communication connection with the PC may be incorrect. Verify that the correct cable is attached and that is not faulty or broken. Verify communication parameters # 27 to # 32 in the printer’s menu system are properly set. 13. Unexpected margins. Extra or insufficient space between the print start position and the top edge of the paper.
ACCEL-7450 15. The last characters of a line are printing on the next line below and at the far left of cut sheet forms. Verify menu item # 7 RIGHT PAGE WDTH is set to NO. This is the factory default value. Move the left paper guide so the paper loads further to the left by at least the number of characters printing on the wrong line.
