    You know, sometimes the key to solving a quality problem is finding the right test page to make the problem reproduceable. I can think of various occasions when I pulled out every test pattern that I have before finding the right image. It a great first step to solving the problem, if you can reproduce the problem. =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

      One last bottom line, Test Charts do nothing when trying to calibrate a customers Network Design prints and Layouts from Adobe Photoshop, Quark, and other Color Management Programs.

                      Re: Test charts

                      Hm, yeah, kind of funny that Teckat is leading the charge to Ban All Test Charts, when it was his post, from back in May, of the Canon standard that got me searching...

                      Here's my contribution:

                      Got a million of em. Let me know if there are any special requests.

                      ***

                      As to the question of whether To Use a Test Chart or Not to Use a Test Chart, why would I be afraid of the judicious sharing of sample images with my customer? You know they just test it for themselves the second you leave. Do I need a call-back? The trick is using a test file that showcases the devices strengths, while declining to shove in their faces, in all its glaring detail, the normal limitations of the machine. (Those are for me, before I even think about printing a final sample for the customer.)

                      Ideally, I'll choose an image that most closely represents the customer's normal day to day usage. Sometimes, with a Fiery driven machine, I can collect something from the held or printed queues. If they generally print business documents with 12% color, don't show them an 11x17 GATF test file! If marketing is their business, you may need to plan for full coverage skintones. It's all in the application.

                          I don't use Canon color test charts/& have not used them in the past 9years-

                          They are useless in quality production accounts/I have no intention to trick customers/ I leave that up to the idiot salespeople -
                          When I see a color test chart at a customer, it goes in the garbage/ I then sit down with the customer to review their expectations on color/ all of these Canon color printers are different/

                          if a poster asked for a color chart, I'll provide it

                            I am based in the workshop so I use test charts a lot and this is one of my favourites

                            Capture.JPG

                            The grey bands on the sides work well to identify faults with drums and developers.

                              those Gray bands are deceiving / mirror optics & enviorment conditions of printer come into play /
                              this does not help with direct network prints-

                              on iR's that have no primary wires / those sheets are a waste of time


                              use your PG Test prints to identify ITB/Developer issues
