秋山浩子 3 I ordered a set 4 color toners for my NEC PR-L5800C printer.I printed about 200 pages full of color with them today and everything looked great.The next day I printed 10 pages and the color did not "stick" to the paper.I noticed that after around 10~20 prints, the prints will be all right again.So, if the printer is kind of "cold" (like in the beginning of the print job) you should not print color.This is inconvenient, and I lowered my rating from 5 stars to 3.
