Issue Description:

• Poor fusing and smearing print when running normal 20-24lb printer paper (75-90gsm).
• Paper type identified as “Light” rather than “Normal” causing the fusing of the toner to weaken over long print jobs or on different quality papers.

Service Technician steps:

It is not necessary to send a Service Technician out to change this setting unless needed by contract.

Noted from firmware: ljM601_602_603fw_ 2302786_433718.bdl – 3-24-14 THROUGH firmware: ljM601_602_603fw_2305090_ 000468.bdl 6-10-15

As this is a user setting which firmware should not change, the first 3-24-2014 version actually did change the plain setting to “light.” However even though the version after 6-10-15 is correct, the user/tech still has to manually change this. (Or if anyone performs a cold reset, partial clean, or format disk.)
