Color Laserjet 2600n Windows 7 -64 Bit Looking for HP Toolbox

I'm having trouble finding the HP Toolbox.    I have a Color Laserjet 2600n.   OS is Windows 7 - 64 Bit.  When I print checks, I notice a slight shadowing of the numbers.  Thinking it may need cleaned, but I cant find my toolbox anymore and have to tried to look online.  I saw something regarding there was no toolbox for Windows 7.  Is this still the case?  When I print on paper everything looks fine.  Also, anything I print that has red in it doesnt not print very well.  This has been a problem for several years.   I had XP until March 2013 and then got a new computer.  Before the computer switch I cleaned and aligned the printer several times, but still no red print.

Thanks,
