The really sad part of this story is the comment section, here's a feel good story with a little bit of mystery added in and these know-it-all clowns have to come in and act like they are the world's foremost authorities on old cameras and film and rain on her parade. i.e. the film is destroyed, there are thousands of those cameras around, try this developer-no that one sucks use these guys. I'm afraid we are becoming a nation of know-it-alls. I see it all the time in so many photography related blogs, its what attracted me to this one. I read one blog string and someone made a disparaging remark and the rest of the crew involved told them this won't be tolerated here. I sure hope so. This is supposed to fun teasing is one thing but I've seen it get downright cruel. It just drives people away. Now that I'm done with my Sunday Sermon I hope you all have a wonderful day.
I'm not sure whether you said you had tried this, just try uninstalling the printer entirely and see if your eraser function comes back with no printer hooked up.
How To Fix Many Problems With Photoshop, ImageReady and Elements
Is Photoshop doing something strange that you just can't figure out? Then it may be time to trash your preferences! This simple procedure cures a good portion of problems with Adobe Photoshop, Photoshop Elements, and ImageReady.
Here's How:
1. Before trashing preferences, check the color mode on the image you are working with. Some of Photoshop's tools and commands don't work in all image modes. (Menu: Image > Mode)
2. If a tool is giving you problems, try resetting the tool to default settings before trashing all preferences.
3. In Photoshop 6 and up, you can reset tool settings by clicking the tool icon on the options bar and choosing "Reset Tool" or "Reset All Tools."
4. In ImageReady go to Edit > Preferences > General and click on "Reset all Tools." In ImageReady for Mac OS X, go to ImageReady > Preferences > General and click on "Reset all Tools."
5. If resetting the tools does not fix your problem, try resetting your preferences.
6. In Photoshop 6 and up, hold down Ctrl+Alt+Shift (Windows) or Command+Option+Shift (Mac) immediately after (or while) launching Photoshop. A prompt will ask if you want to delete the preferences file. Click Yes.
7. In Photoshop Elements, hold down Ctrl+Alt+Shift (Windows) or Command+Option+Shift (Mac) immediately after (or while) launching Photoshop. A prompt will ask if you want to delete the preferences file. Click Yes.
8. In Photoshop 5.0 or 5.5, locate the files "Adobe Photoshop 5.0 Prefs" and "Color Settings" and delete or rename them. They are in the Adobe Photoshop Settings folder in your installation folder.
9. You may want to save a backup copy of your adjusted Preferences file so it can be restored if needed. This is not necessary, but if you want to avoid resetting all your preferences any time you reset them, it can be helpful to have a backup.
10. To backup your Preferences, search for a *.psp file (i.e. Adobe Photoshop X Prefs.psp where X is your version) and make a copy. Note that not all settings are stored in this file, however.
