Print Speed Service Check - Lexmark 2380 - Forms Printer B/W Dot-matrix Service Manual

Print Speed Service Check

Reduced speed while printing the top 2 inch (51 mm) of a job is
normal; for Model 003 printers, the slow down can be eliminated by
entering Setup Mode and disabling TOF Read. The speed of the
23XX printers varies with the font, forms thickness setting and
printhead temperature. Graphics output may print slowly due to data
throughput limitations. Thermal sensing is built into the printhead on
239X printers and protects the printhead from overheating.
Depending on the job content, thermal slowdown may occur after 5
to 10 minutes of continuous operation on 239X-001 printers and
after 10 to 20 minutes on 239X-002, 003 printers.
Print slowdown modes are as follows:
238X-001
239X-001
238X-002
238X-003
239X-002
239X-003
