need envelope print speed - sometime 30k envelopes

Posted on 2006-04-18
Last Modified: 2010-04-12
I have tried an IBM 1572 and HP4350tn with envelope feeders. In both cases the manufacturer stated that printing envelopes would not degrade the performance. Once installed the speed dropped to about 10-20 ppm. Both times the manufacturer tech support says, "Oh yeah. We slowed the print speed on envelopes on purpose". IBM was to save the fuser and HP was to stop smearing of the print. $2000-2500 is the budget. Anything from 40 to 50 ppm would be fine but the envelope printing needs to run at the stated speed. Any ideas?

    I don't know of a printer to perform like you want unless you go to a BIG Xerox BUT (and Xerox would have to be researched) keep in mind that running large quantities of envelopes through a printer will tend to cause an impression on the fuser where the envelopes are running through.  This impression will create two black lines down any other document at the edges of the impression.  

    Hope this Helps!!!    and not toooo confusing.      :-)

    Accepted Solution

    the envelopes are two times morethick than normal paper, becouse of this the amout of electric current that needs to be aplied for the toner placement on the paper is higher and you have more chances of getting some "fog" arounf the letters.
    Also like david523 said it will mark the fuser rolls, also the speed reducing is also becouse the paper is thicker and the fuser is almost at the same temperature( usualy raise 5 to 10 degrees with thick paper) so the paper need to saty more time with heat and beiing compressed on the roller, if this doesn´t happen the tonner may not be well fixed(melted) to the paper and will go out if you scratch it.

    For the budget you have, i see i dark future for you :-)
    Look in Ricoh, or lanier in US for the 45ppm printer, or if you could make your budget 6 times bigger maybe a high volume of 85 or more ppm.

    But you will always get a slowdown of the speed, unless you convinve the technitian to change the paper settings and sensors (ON/OFF) so the printer is mistanken, but remneber you wull hame more probability to have the problems i decrived above.

    hope i helped.

    It seems that every manufacturer boasts of their printing abilities but only face the facts after I send their printer back. is the only site where I got complete information. Hope this helps anyone following me.
