    A Question about developer and my observations

    We've been printing a lot on the 1051 but I have seen an increase in toner usage. More than usual. This morning, I checked counts and noted developer is at 971,000 out of 1,000,000. I know many printers that try to beat all they can out of developer but I'm just not one of them. I remember some time ago, while it was still under service, we started getting a gritty dusting on the sheets. Developer was at 950,000 plus. After further study, we realized it was, indeed, developer beginning to dump. It was changed and grit went away. I guess I've never took note of increased toner usage but recovery box was changed Monday and it is already a tad less than half full. I am wondering if it is anyone else's experience that developer going bad can cause excess toner usage?

    If you are getting H toner then this is the issue..The majority of my 1100, 1052 and 61XX are only getting 1/3 to 1/2 of the copy volume prior to this crappy H toner..In many shops I am replacing developer at 25K (in many cases this is daily). E

    Nothing wrong but I'm wondering where is near 1 million compared to 25k
    Some of our office machines(20-40ppm speed) are nearing 500-600k developer life working with mostly H toner last year.

    I apologize but what does H toner mean?

    H toner for the office machines just meant 1/2 bottles..For production equipment the H was a different toner. It runs, but the quality is not there..I don't think the H toner had the same affect on the color production machines.

    Re: A Question about developer and my observations

    So you're saying the toner that is in the pipeline now isn't 119,000 sheets yield at 5%? $179.00 a bottle???? Machine just stopped printing, telling me to exchange toner recovery bottle. It was full! I checked it this morning and it was a tad under half. I changed it Monday. No way I've run anywhere near 357,000 sheets since Monday. Not even a third of that. But I just put my 4th and last bottle in this morning. I'm coming up with 42,000 11 x 17 copies, mostly type, since Friday. 3 bottles of toner?? Wow. Def something wrong here.

    Yes..if it's H toner we are seeing massive drops in impressions per bottle. I have a few machines it does not seem to affect, but anyone with graphics or a high %...it's really bad. Again this only seems to affect the B&W production TN 014, 015, 016, 017..All of this toner is exactly the same, just different bottles. E

    Re: A Question about developer and my observations

    Its not just developer is high that can cause toner issues what is drum volume. This can also cause high toner useage. 25k is a bit much to be doing. 500k would be ok. Are you running the dev adjustments?

    I'm not really sure what this statement means. We regularly get 900K+ out of developer with no issues. Drum is 544,000 out of 1,000,000. I usually change drums around 750k. Very few last to 1,000,000. This is a new issue to us. Never seen toner consumption like this before. I found a pre fire bottle of TN011. We're going to see how long that one lasts. I run drum and developer adjustments when I install. Never had to do either in mid flight except an occasional drum sensitivity adjustment.
