Be prepared to churn through a LOT of ink as it cleans, tests, etc. If it is low on any carts, have new ones ready because once it gets to an empty cart, everything stops until replaced.
If it had primarily full carts when stopped, just turn it on, have paper handy, keep fingers crossed and wait - it's a slow process. BUT also make sure to have a new waste cart on hand if the existing one is not in good shape. The inks purged for cleaning will fill it fast and again, the process will stop dead if that registers as full at any point.
We're in a not too dissimilar situation.
Our 1000 was left unused for the better part of a year due to C19, etc., (own stupid fault), BUT in our case, most inks were at 10% when last used. We tried restarting and 1 cart emptied after app. 20 minutes of self-clean/diagnostics and it's not one I have on hand. Almost all other inks are at or below 10% and odds are they will empty (fill tubes) before process over, requiring replacement. The head was fine, but we don't know how many, if any, ports on it are clogged and thus if it has any available ports remaining before it needs replacement.
A full set of inks is C$950 + waste cart. A new head is also app. C$900 and a new Ipf-1000 is (on sale now) C$1300 with a complete set of inks. So our choices come down to:
a) Buy new ink set, continue process and hope that head can be cleared w/o killing too much ink and all good with head. Out C$950.
b) Do (a) and if fails, buy new printer, use partial inks from old one as spares (or vice versa). Buying new head + ink set not cost effective. Out C$2250 ($950+$1300)
c) Kick self in ass, buy new Ipf (awesome printer), save the 1-2 inks that are in good shape as spares and sell old printer for parts. Out C$1300.
Option C is our likely scenario. If out inks were all in strong shape, we'd go for A and keep fingers crossed.
Good luck.
