Thought it would be fun to list my canon imagerunner wishlist items:

1. I wish the jitter issue in medium grays that sometimes occurs at present would be resolved completely
2. I wish you could adjust CMY or K density on the fly instead of having to stop, adjust, and resend/rerip the job
3. I wish the machine had "up front" CMYK density adjustments instead of having to click a few levels of menu deep... having C+-M+-Y+-K+- buttons on the touchscreen first page would be a timesaver when using drums to the end of their life
4. Likewise, I wish you could adjust position (layout) on the fly +/- .01 to .05 without having to cancel and restart the job to adjust the subtle position
5. I wish the last job were stored in the printer's (large) memory for instant reprint instead of having to rerip when you click "print" for the last finished or cancelled job
6. I wish there were a mechanism that could print a solid area of color on a sample, scan, and then "adjust" across the drum for weak areas that currently show up as light narrow to 1/4" wide streaks as the drums get older, especially black. I realize it wouldn't be perfect, but it could likely make a nice improvement if there were at least some digital compensation for the weak spots across the drum.
7. I wish the optional bar graphs displaying drum yield under the main status screen had an option to replace them with numerical values; it's really beyond 100% yeild that they become critical so you know when the drum is about to give way entirely or begint to leak, so the graph that only shows up to 100 and in 25% increments is not much use.
8. I wish the waste toner plastic sensor hole covers didn't cloud with toner when the waste toner containers were only half full requiring them to be cleaned unnecessarily.
9. I wish there were a high-gloss toner option in additoin to the matte finish toner.

Ok the Xmas is near!!!

I am so sorry for your Wishes cause it will not be granted since those are the Limitations of the IRC. Besides, IRC is not for Graphi Arts.

I suppose with everything there will always be easy improvements that could be made to make a product more useful; and of course using the "entry level" machines, cars, etc. things intentionally left out or made difficult or intentionally detuned to sell the next level up (e.g. some of the hardware in the $5000 fiery rips that could be so much better with $250 of hardware, hardware not added as it's reserved for the $15000 RIP) I tend to agree though that we will likely not see these things in future models, unless there is increased competition from konica or xerox - for example why use software to help customers extend drum life, when you're selling the drums themselves; why store a rasterized job in memory when not doing so will sell the customer a more expensive rip; etc. etc. Still would be nice additions to make a good series of machines even better.
I remember when they were first released they were not thought to be much at all. Now that we've run 308 miles of paper through ours, I'm pretty happy with them.
