Hi 
There is no need when:
- After a cleaning a printhead that looked bad on print test, now looks good
There is need to replace just wiper when:
- Horizontal lines (usualy big areas, 2mm or more) appear usually in all or some colours and usually in the center of the print test
- Drops under the printhead after a cleaning
There is usually need (not always is the problem, but I suggest you have always one in stock) to replace the complete pump, wiper, etc when:
- After a cleaning, printhead tests looks similar or worse, and worse and worse
An advice is ALWAYS clean the wiper after a cleaning or before a cleaning, and replace as fast as you can when is not completely flat (like a new one). Always have at least 1 or 2 since is a consumable, and if you use oem inks, sometimes they are more aggresive and will shrink the wiper fast, curving it (and other problems that wouldnt fit on the thread!.
One week is better than nothing of course, but you should clean at least the wiper and the suction cap rubbers daily (it worths the 30 seconds required...)

Always clean the wiper of the capping machine before or after cleaning it, and replace it as soon as possible if it is not fully flat (like a new one). Always keep at least 1 or 2 on hand because they are consumables, and if you use OEM inks, be aware that occasionally they might be more aggressive and cause the wiper to shrink quickly, bending it (as well as other issues that wouldn't fit on the thread!
